Low beam lamp Largus - selection and replacement. Replacing the low beam bulb on Lada Largus

January 18, 2016 Lada.Online 110 379 1

During operation of the vehicle, the headlight bulbs may burn out. If you decide to replace them not at the dealer, but yourself, we recommend that you first study the instructions. The fact is that on the Lada Largus the lamps in the headlights change with some features, which we will discuss later.

You can replace faulty lamps yourself using the methods described below. If replacement seems difficult, it is recommended to contact a LADA dealer.

WARNING!

Before replacing a lamp, ensure that the associated signal light is turned off.
Wear protective gloves when replacing lamps.
Do not touch the glass bulb of the lamp with your bare hands. Hold it by the plinth.
Halogen lamps are under pressure and may explode when replaced. This may cause injury.

ATTENTION!

For normal operation of the lighting and light signaling systems, use lamps recommended by the factory.
Failure to comply with these recommendations may lead to destruction in the form of cracking or melting of the diffuser due to its overheating.

Choice

First of all, it should be said that the low beam lamp for the Lada Largus uses a halogen H4 standard, i.e. contains two threads and is responsible not only for near, but also for distant lighting.

Currently on the market you can find such lamps from a variety of manufacturers, among which are the following:

Bosh;
Osram;
Philips;
Narva, etc.

In addition, domestic Mayak light bulbs have recently proven themselves to be quite good. Their advantages include not only low price, but good quality.

H4 standard lamp

Advice! It is advisable to purchase light bulbs in specialized stores, since recently a lot of counterfeit products from China have appeared that quickly fail or produce poor-quality light.

Of course, when choosing lamps you need to pay attention not only to the brand, but also to the following characteristics of the lighting element:

Characteristics	Optimal parameters
Brightness (light beam power)	Up to 1550 lm
Lifetime	Up to 1500 hours
Power	45-60 W

Standard halogens provide an unnatural yellowish glow. However, recently light bulbs have appeared with a bluish glow. People call them pseudo-xenon.

However, it should be noted that such light illuminates the road well only in dry weather. In fog or rain, ordinary lamps are preferable.

Moreover, in bad weather, even the expensive “xenon” and “LEDs” are inferior to the latter, the power of the light beam is one and a half to two times more powerful than that of halogen bulbs. This is due to the fact that the light of these elements has insufficient penetrating power.

Note! To install xenon and halogen lamps, you should contact a service center for help, since this work requires the installation of additional equipment and changes to the software. Accordingly, the installation of such lighting is quite expensive.

About related faults

Replacing the low beam bulb on a Lada Largus

A lighting device for any purpose that refuses to perform its function can signal to the owner of the Lada Largus that the fuse is faulty. If it is discovered that the jumper in the fuse link has burned out, then such an element requires unconditional replacement, which also means replacing the marker light bulb. This is quite easy to do. The mounting block is located on the left edge of the interior panel in close proximity to the unit for switching the modes of lighting devices. Here are the inserts numbered F1 - F39. Fuses numbered 9 and 10 are responsible for ensuring the operation of the low and high beam, respectively for the left and right headlights of the Lada Largus car.

Insufficient contact at the terminals in the fuse block can also cause problems with the normal functioning of the head optic components.

There may be cases of premature burnout of the contact inside the lamp itself or banal oxidation of contacts with the ground. The last option can be easily eliminated. To do this, it is necessary to thoroughly clean the contacting surfaces of the cable lugs. A wire brush will do.

If these methods do not give the desired result and the functionality of the Lada Largus lighting devices is not restored, then you will need to contact professionals for a more thorough diagnosis of the causes of the malfunctions and their subsequent elimination.

Standard replacement procedure

Replacing the low beam lamp, as well as the high beam, begins by disconnecting the on-board power supply. This precedes all electrical repair work. In this case, a special switch is turned or the negative terminal is disconnected from the battery, which avoids accidental short circuits or erroneous connections during installation.
The place where the Largus lamp will be replaced is determined. There, the rubber plugs covering the electrical components are removed, and two metal antennae are opened in front of the car owner, fixing them in the reflector. They are separated so that the used parts can come out of their seat without damaging the housing.
Next, you need to disconnect the plugs from the wiring that was previously disconnected. Here it is worth paying attention to the order of arrangement, otherwise, during the installation of new parts, everything can be mixed up and they will have to be changed again.
After connecting the plug with wiring to the new parts, they are mounted in place and secured with antennae. You should try not to touch the flasks with your hands, as this can lead to their rapid failure.
If the light is dim during lighting, and the headlights flash when you turn on the headlights, then it is imperative to restore the contacts of the wires with the vehicle body. This is especially true for a marker lamp, because the fat that gets there begins to evaporate when heated and can cause ignition.
At the end of this procedure, you need to put on the rubber plugs and secure all the parts in their places. After this, the car will be ready for use and the driver does not have to worry about malfunctions of the Lada Largus lighting fixtures.

As practice shows, in modern domestic cars, one of which is the Lada Largus, lamps with directional luminous flux are most often used. The essence of such lighting is a reliable view in front of and behind the car. At the same time, inconvenience to other traffic participants heading towards the driver or driving behind is excluded.

How to choose a lighting element

The range of lamps for installation in car headlights is very extensive. However, there are two factors that significantly limit your choice:

the design of the headlamp block does not allow the use of any options you like;
code requirements that expressly prohibit the installation of any elements other than those originally used by the manufacturer.

In the Lada Largus car, the functions of low and high beam are performed by one double-filament halogen lamp. This is convenient as it allows you to save space under the hood and reduce the size of the headlight unit. One tungsten filament produces a beam of light of greater brightness, directed primarily horizontally (high beam), and the second creates a beam with an opening angle of 30°, of which 10° are directed above the horizontal, and the remaining 20° below it.

The ability to reduce the size of the headlight unit results in the need to change the light bulb when any filament fails, even if the second one works quite reliably. In addition, you always have to change both lamps, left and right, since for high-quality lighting you need a set of two lamps selected according to their characteristics.

Lada Largus lamp base

High and low beam are realized using one light bulb with h4 socket. In addition, the following types of base are used for different positions:

h11;
P21/5W;
PY21W;
P21W;
WY5W;
W5W.

What kind of bulbs are in the headlights?

Low and high beam lamp – H4, power 12V, 60/55W;
Bulb dimensions – W5W, power 5W;
Front turn signal lamp - PY21W;
Fog lamps - H11, power 12V, 55W.

Block lights

Structurally, each block headlight of the LADA Largus station wagon consists of two sections. One contains:

"marker" lamp (W5W).
double-filament lamp for low and high beam (type H4);

Nearby is the section in which the PY21W turn signal lamp is located.

The headlight unit is dismantled when it is damaged or needs to be modified (tuning).

Replacing the headlight

Before you begin work related to replacing the headlight, you must:

Secure the station wagon using the handbrake.
Remove the key from the ignition.
Remove the negative wire from the battery terminal.

The dismantling of the headlight block of the LADA Largus station wagon begins by first removing the front bumper. This operation is shown in detail on the video page:

After this, access to the fastening elements in the lower part of the case will open. Next, you need to disconnect the electrical wires:

going to the H4 type lamp. To do this, remove the cover 3 and disconnect the pads;
remove the sockets for the direction indicator lamps 5 and indicator lamps 7;
remove the actuator of the headlight hydraulic corrector (if equipped) from the headlight housing, to do this, slide boot 4 along the cable and unclip the fastening latch.

after this, you need to unscrew the fastening bolts (items 1, 3 and 4) located around the perimeter of the body part (2);

push the headlight housing forward a little and remove it.

The new headlight unit is installed in the reverse order, maintaining a uniform gap between housing 2 and body parts.

Adjusting the luminous flux

After carrying out any work related to the head optics of the LALA Largus car, it is mandatory to check and adjust (if necessary) the direction of the luminous flux of the switched on lamps. To do this, it is best to contact a specialized service station, equipped with special instruments and staffed by qualified specialists. However, in case of emergency, such an operation can be carried out independently and without the necessary equipment. In practice, there are several ways to check and adjust headlights. You can see one of them by watching the video:

Replacing lamps in a headlight

Among the sudden malfunctions that almost all car owners encounter, one of the first places is the failure of head optics light sources. These include lamps:

low/high beam;
direction indicator;
Dimensions indicator.

All of them are located inside a separate headlight and changing them, if necessary, is not difficult.

Replacing the low/high beam lamp

Change the low/high beam lamp in the LADA Largus headlight in the following order:

remove the protective cover;

disconnect the block with wires;

pull out the rubber seal;
pressing on the spring holder, remove it from under the latch;

Carefully releasing the holder, carefully remove the burnt out lamp.

The new lamp is inserted into the reflector hole and secured using standard fasteners. Then all the removed parts are returned to their places.

Attention! Lada Largus uses halogen light sources, the glass surface of which is not recommended to be touched. To avoid darkening of the flask when heated, it is recommended to hold them by the base.

Replacing light bulbs on Lada Largus - photo, video of replacement

Constant use of the car will one day lead to the need to replace light bulbs on the Lada Largus. This is easy to do at a specialized service station, but you can do all the necessary work yourself. To achieve the desired result, you need to carefully study the instructions. This is due to some nuances that should be taken into account when replacing light bulbs on a Lada Largus. Let’s talk about all these subtleties of work in more detail.

Replacing low and high beam bulbs on a Lada Largus

Any replacement of light bulbs must begin with turning off the power. These actions are required for working with electrical equipment of a car. The power is disconnected by turning a special lever or removing the terminals from the battery. This way you will completely eliminate short circuits caused by improper connection of wires. You need to understand that one bulb is used for the low beam of Largus, and the second for the high beam. The average lamp operating life ranges from 2-4 thousand hours. You can gain access to the left light by removing the battery.

Turn the lid counterclockwise;

Installing the working light bulb in the Largus lantern is carried out in the reverse order. Remember that you should only hold the lamp by the base, and it is advisable not to touch the bulb. As a last resort, you can wipe the light bulb with a lint-free microfiber cloth. You can watch the correct process of replacing a low beam light bulb in the video:

Replacing side light bulbs on Largus

If it is necessary to replace this lamp, the entire lamp must be removed. This is the only way to ensure access to the side lights of Largus

After dismantling, we disconnect all power wires with extreme care and attention. After disconnecting the power from the battery, you need to remove the front bumper, which serves as additional protection for the dimensions. Ideally, work is carried out wearing sterile gloves.

If the device was touched by negligence, it must be treated with a lint-free microfiber cloth.

If the device was touched by negligence, it must be treated with a lint-free microfiber cloth.

We remove the fender liner by removing the fasteners;
We remove the socket with the light bulb by turning it in the direction of the clock, and for the right side you need to turn it in the opposite direction;
Remove the burnt out lamp from the base.

To replace the backlight on Largus, turn the socket counterclockwise. Then carefully connect the 2 wires to the battery. And now all that remains is to install the working lamp and carry out the assembly. Installing all components in place is carried out in the reverse order and does not take much time.

Replacing turn signal bulbs on Lada Largus

It is impossible to get to this lamp from the engine side, so we will replace it from below the car.

We remove the fender liner by removing the fasteners; We unscrew the socket with the burnt out lamp counterclockwise; Remove the lamp by carefully pressing it and at the same time turning it counterclockwise.

Reinstalling all parts is carried out in reverse order.

Replacing bulbs in fog lights

As in the previous case, the replacement is carried out from below the car.

We unscrew the fasteners and dismantle the fender liner;
Unlock the latch and disconnect the block from the lamp;
Carefully turn the light bulb counterclockwise and remove it from the socket.

Installing the work lamp is carried out in the reverse order.

Interesting to know! In reality, replacing light bulbs on a Lada Largus is much easier. We have described the ideal and correct option. Having trained your hand, you can do all the work with the least amount of effort and time.

Let's sum it up

It is imperative to monitor all lighting elements and change them on time. Reduced efficiency of light bulbs can easily lead to dangerous situations while driving!

Dimensions

A special feature of this procedure is the preliminary dismantling of the headlight unit, under which the side light lamps are located. After this, it is necessary to disconnect the wires from the battery, which is done with extreme care.

Removing the front bumper will allow you to get to the cover that protects the dimensions. Since they come into contact with other light devices, it is advisable to carry out all procedures using sterile gloves. If any device has been touched, it must be wiped with a clean, lint-free cloth.

To replace the side light bulb in Largus, the socket of the old part is turned counterclockwise. The black and yellow wires connect it to the battery, so it turns off from them. A new part is installed in this place, and assembly is carried out in the reverse order.

Low and high beam

One lamp is responsible for low and high beam. Its resource is 2000-4000 hours. To gain access to the left headlight unit, you must remove the battery.

Turn the lid counterclockwise;
Remove the cover by releasing the latch.

Remove the block with wires by unclipping the lock;
Remove the rubber cover by prying it off by the edge.

Unscrew the lamp clamp to the side;
Remove the headlight bulb.

Installing a new lamp in the Largus headlight is carried out in the reverse order. You need to hold the lamp by the base; it is not recommended to touch the bulb with your fingers. If necessary, wipe the flask with a microfiber cloth that does not leave lint. The process of replacing the H4 lamp is also shown in the video:

Conclusion

You can get additional useful information on the discussed topic from the video in this article.

A note about what kind of lighting lamps are installed in the Largus headlights; which of them are low/high beam, and which are responsible for the side lights. How to change lamps yourself. How much do originals and analogues cost in Yaroslavl?

Good day, future and aspiring gentlemen Largusovod!

On Largus, the low/high beam and headlight lamps often burn out. At least for 70 thousand I have already changed it five times on each side.

The following light bulbs were installed on my car:

1. Low/high beam: halogen, Osram H4 12v 60/55w. (art. 64193). Price from 109 rub.

There are many analogues. Here are some of them:

370 rub. General Electric (34454)

117 rub. Valeo (032007)

2. Front dimensions: halogen baseless 12V Osram (art. 2825). Price from 17 rub.

26 rub. Lynx (L12805)

9 rub. Fortluft (2825)

3. Rear dimensions: two-pin with filament, base BAY15D. Beacon 12V P21/5W.

from 56 rub. Fortluft (7528)

They burn out less often. I changed it only once in the right lamp. This is what she looks like:

How to replace headlight bulbs

1. First, remove the protective cover. It turns a little, then a small latch is released.

2. The block with wires is removed.

3. Remove the rubber protective sleeve.

4. The lamp is pressed U -shaped clamp. It needs to be pulled to the side and back.

5. Take out the lamp. Remember its orientation. Two teeth at the bottom, one at the top. And if you look at it from the side of the headlight, the inscription (marking) will be on top.

6. Install a new lamp. You should not take it with your bare hands, as greasy marks from the pores will remain on the bulb and the lamp will fail faster. This applies to all halogen lamps. It is better to hold it by the plinth or use a microfiber cloth.

7. Assembly is carried out in reverse order. First the clamping clamp, then the rubber bushing and finally the top cover.

How to replace front markers

There isn't much action here. The main thing is to get to the cartridge and turn it 90 degrees. The most inconvenient thing to change is the battery side. Not enough space. If your hand is large, it is better to remove it.

Thus, the procedure is as follows:

Found a cartridge
They turned it over and took it out
Removed the lamp
It is better to wear gloves when installing a new lamp into the socket.
Then we insert the cartridge back into the headlight and rotate it 90 degrees.

Troubleshooting Some Problems

If, after replacing the lamp, the low beam on the Lada Largus still does not light up, the cause of the malfunction may be a blown fuse. Replacing them is even easier than the paws, since they are located in the cabin, on the left side of the steering column.

Two fuses are responsible for the low beam:

F9 – left headlight.
F10 – right headlight.

Note! Even if the fuse is not visually damaged, a new one should be installed in its place.

Fuse box diagram
Often the cause of a malfunction is poor contacts of the fuse terminals. In this case, you just need to clean them.

It should be noted that there is no low beam relay on the Lada Largus, therefore, if replacing the fuses did not produce results, all that remains is to check the contacts in the headlight itself, which could have burned out or oxidized.

Often the light goes out due to poor contact of the machine ground wire. In this case, the problem is also solved by thoroughly cleaning the contact. If it was not possible to restore the light, you need to contact a service center for help.

Here, perhaps, are all the instructions for correcting the most common VAZ wiring faults.

Lighting elements of Lada Largus

It is worth noting that all lamps used in headlight lighting of Lada Largus cars are divided into three types:

halogen;
xenon;
LED

The most common type of headlights for low or high beam are LED variations, since these are the most powerful and efficient lamps in terms of energy conservation. In addition, they can be used for brake lights, turn signals or markers.

Replacing a low beam lamp on a Lada Largus: how much does it cost?

The ability to independently replace light bulbs in your car's lighting fixtures is very useful, as it allows you to save both time and money. Today we will see that replacing a low beam lamp in a Lada Largus is a fairly simple task that anyone can do.

General information about this model

The first LADA Largus car rolled off the AvtoVAZ assembly line and went on sale in 2012. It was a Romanian Dacia Logan MCV, adapted for the Russian market. The car is produced to this day and has four modifications:

Largus R90 – passenger station wagon for five and seven seats;
Largus F90 – cargo van;
Largus Cross is essentially the same five- and seven-seater station wagon, but with increased ground clearance and slightly different exterior and interior trim;
Largus CNG – production started in 2022. Modification with gas cylinder equipment.

Passenger station wagon (left) and Largus Cross Note. The first Largus rolled off the assembly line a year earlier - in 2011, but was intended for sea trials.

What lamps are used

Before we figure out how to change a light bulb on Largus, let’s determine what lighting devices are used in the headlights of this car. The Largus headlights have only three lamps:

Low/high beam. Halogen double helix with H4 base. The power of the spirals is 55 and 60 W, respectively.

High and low beam lamp for Largus

Parking lights. Incandescent bulbs with W5W socket. Power 5 W.

Front side light bulb Lada Largus

Turn indicator. Incandescent bulb with an orange cylinder with a PY21W base. Power 21 W.

Front turn signal lamp Lada Largus

Closer to the side there is a turn signal light, in the center there is a device responsible for high and low beam, and underneath it is a side light bulb.

So, we figured out the types of lamps. A bulb with an H4 socket is responsible for the low and high beam. All that remains is to decide which one to choose, because the range of light bulbs with such a base on the modern market is quite wide.

But by what criterion should you choose? Price? Quality of light? Life time? Colorful temperature? All these parameters are important for any light bulb, but, alas, they often exclude each other - cheap cannot be of high quality, and vice versa. This means that we will choose according to the price/quality ratio and our financial capabilities, focusing on the brand.

According to independent experts of the company, the price/quality ratio of the lamps was distributed as follows:

Bosch;
Osram;
Philips;
Narva;
"Lighthouse".

Of course, the above rating does not mean that you should only take Bosch. The products of this manufacturer are quite expensive, although they have the highest characteristics.

Domestic Mayak lamps, for example, are inferior to Bosch in many respects, but are much cheaper than the latter.

Thus, the choice will depend not only on the desire to get the best, but also on material capabilities.

Important! In order not to buy a Chinese counterfeit instead of Bosch or Narva, we will only buy light bulbs in specialized stores. And the fact that the same lighting device on the nearest market costs half as much should not rejoice, but be alarming.

What do we need for work?

In order to replace the lamps in the headlights of the Lada Largus, we will need:

Torx key T-20;
clean cotton gloves;
replacement H4 bulbs.

Let's start replacing

If everything is ready, then you can start replacing the low beam bulb. In order to gain access to the Lada Largus headlight, you need to remove the plastic fender liners. Take the Torx key and unscrew the screws securing it.

To remove the fender liner, you need to unscrew several screws

There are two headlights in front of us: below is the fog light (PTF), above it is the head light. Naturally, we need the latter. For clarity, in the photos below, all actions will be performed with the headlight removed. We will work from under the wing.

We find the hatch for the high/low beam lamp. It is closed with a protective plastic cover. Press the latch and remove it.

Under it we see a rubber boot, from the center of which protrudes the light bulb power connector. We remove it from the lamp by simply pulling it out.

Now you can remove the boot itself.

In front of us is a light bulb, pressed with a spring clamp. We press our finger on the upper part of the lamp clamp and remove it from under the hook on the reflector.

After this, simply fold the spring down, freeing the lamp.

Now nothing holds the lamp

We take it by the body and remove it from the reflector. It's time to put on gloves, because you can't handle the bulb of a halogen lamp with bare hands: the remaining particles of sweat on it will cause local overheating of the glass, and it will simply melt. If you don’t have gloves, then hold the new light bulb only by the base, without touching the bulb.

If we accidentally touched the flask with our bare hands or simply got it dirty with something, we wipe it with a napkin soaked in alcohol.

We install the device in place of the burnt one, monitoring the position of the keys on the base. One of the keys looks up, two symmetrical to it look down. We fix the lamp with a bracket, put on the boot, power supply, and protective cover. Now you can check if everything works, and if so, then install the fender liner in place, securing it with screws.

On a note. Some craftsmen do without removing the fender liners, performing all manipulations from the engine compartment. But, firstly, for this you need to have the hands of a pianist, and secondly, when working with the left headlight, you will still have to remove the battery.

In order to climb through all these pipes, you need to have the hands of a pianist and remarkable patience

What to do if the light still doesn’t work

If after replacing the lamp the low beam still does not work, you will have to look for the fault. First of all, we check the fuses responsible for the corresponding headlight. They are located in the mounting block, which is located on the left side of the driver and is closed with a decorative cover.

Location of the mounting block in Lada Largus (decorative cover removed)

The low beam is controlled by fuses F9 and F10 for the left and right headlights, respectively. You can find them based on the following photo:

Numbering of fuses in the interior mounting block of Lada Largus Useful! The numbering and location of the fuses are marked on the inner surface of the decorative cover. There are also spare inserts and tweezers for replacing them.

If the fuses are intact, then you will have to look for the problem in the wiring and connecting blocks. The contacts in the pads may oxidize, the wire may fray or, due to poor contact, burn away from the pads. If we have electrical knowledge, we look for it ourselves.

If not, contact a qualified specialist or even a regular electrician.

So we learned how to change low beam bulbs in a Lada Largus ourselves. Now there is no point in wasting time and money on a trip to the service station - after all, you can do everything yourself in a matter of minutes.

The procedure for replacing the right and left headlight bulbs is the same.

Location of lamps in the headlight: 1 – turn signal lamp; 2 – headlight adjustment mechanism; 3 – screw for adjusting headlights vertically; 4 – headlight lamp (low, high); 5 – side light lamp; 6 – horizontal headlight adjustment knob

Open the hood and disconnect the negative battery.

Replacing the head lamp (low and high beam)

Headlight bulb H4 - halogen, double-filament.

Turn the plastic cover, press the lock and remove it (in the photo, for clarity, the headlight is pulled out of the cavity in the body)

After releasing the lock, remove the wiring block from the lamp.

Lift the edge of the rubber sealing boot and remove it from the headlight.

By pressing the spring clamp of the lamp, disengage it from the reflector

Lower the latch

And remove the headlight bulb (low and high beam) from the headlight housing

Insert the new lamp, secure it with the spring holder, install the rubber seal, attach the wiring block to it and replace the plastic cover.

Replacing the turn signal lamp

Turn signal lamp PY21W (orange).

Replacing the turn signal lamp in the headlight without removing the fender liner or battery can be problematic due to difficult access. Some drivers are able to do this, some are not. If you cannot make a replacement with direct access, proceed as follows:

Jack up the car, remove the wheel, unscrew the two screws securing the fender liner from below to the bumper and one screw in the arch. Bend the edge of the fender liner and slide it behind the brake disc. Access is open.

Release the connector lock

And disconnect the wiring block from the lamp socket

Holding the socket, turn it and remove it from the headlight along with the lamp

By pressing and turning the lamp, remove it from the socket

Install the new lamp in reverse order

Replacing the side light bulb

Side light bulb - W5W.

Replacing the side light bulb in a headlight directly can be problematic due to difficult access. Some drivers manage to do this, some don’t, and some only do it on one side. For an easy, albeit more time-consuming replacement, do the following:

For convenience, you can disconnect the turn signal lamp connector (see above)

Turn the lamp socket (for the right headlight - counterclockwise, for the left - clockwise)

And remove it from the headlight housing

Remove the baseless lamp from the socket and replace it with a new one.

Addition (owners' experience)

HEADLIGHT BULB OFTEN BURNS

Today I was traveling with a friend. He complained that he was tired of changing the headlight bulbs; they burned out catastrophically. He says that he was driving an auto electrician, who said that it was necessary to install an additional relay. What kind of relay? If the relay is a regulator, then what does the additional thing have to do with it? Isn’t it easier to select it according to the stabilization voltage 13.8v - 14.2v. It seems that the whole point is that now the low beam is used as daytime running lights and the life of the lamps is simply not enough for a long time, plus the poor quality of the lamps.

My headlights are constantly on - they usually last for 20-40 thousand km. I install the most ordinary but “branded” lamps - Narva or Osram. If they often burn out, then the voltage in the network may actually be too high, it’s worth checking. If you use the cheapest, “leftist” manufacturers, then they can really often burn out.

Still, LED daytime running lights rule. We’ll have to figure out how to put them on our devices. In principle, there is a classic circuit of two relays and two diodes, but without having the electrical circuit of the device it is still difficult to judge; additional decoupling may be required.

What for? They won't pay for themselves soon. It's easier to change light bulbs.

You probably won’t find a better stabilizer than a battery (read very large capacity). From theory it is known that everything is electronic. devices burn out at the moment of switching on or off (so-called transients) when the voltage increases several times for milliseconds (pulse). If an electrical device cannot withstand this, it means it is either of low quality or has exhausted its service life.

If the generator produces 16 volts, sooner or later the lamps will light up. The lamp, while cold, has low resistance and surge occurs when turned on. Arm yourself with a voltmeter and take the time to measure the on-board voltage with the engine running! And then draw conclusions on a specific car

I completely agree. Excessive voltage in the on-board network due to a bad regulator relay is not good. However, my experience says (I don’t pretend to be the ultimate truth) that either the relay-regulator flies completely and the voltage jumps to 30-40 volts, which the generator produces without a RR, or the RR underestimates the voltage, the battery is undercharged, and even more often the diode flies out one of the phase (there are three) windings of the generator is also undercharged.

Well, yes. It is somewhat more difficult to burn an LED by excess than a lamp. And it would be a good idea to install a 12 volt stabilizer on board the network. Well, of course, except for the starter. Well, that’s in theory. But the guarantee providers will treat this poorly. There is also an option to install a smooth ignition circuit for the lamps, when the voltage is not applied to the lamps immediately, but with an increase, which eliminates current surges when turned on. And the lamp becomes almost eternal. this is the topic. Although for the stops and turn signals this is extra ignition time, which is very bad. So, LEDs.

After buying the car, a couple of months later the original Osram lamps burned out every 3 days. Replaced them with Philips. They are still running, they have already driven 40 thousand since the replacement, and in about a year

Why do light bulbs burn out? It's not all that complicated. In Logan-like cars, engine speeds go up when cold. And as a result, the generator rotates faster, which means it produces increased voltage. Let's add to all this a cold, drained battery that automatically begins to take on more charge. + some kind of turned on stove. All this together affects the functioning of the brain of the regulator relay. They are there, even though they are chicken, nevertheless. Therefore, turning on the headlights on a cold, unstable engine, you can catch an impulse to increase the voltage of the on-board network, skipping the regulator relay. Which leads to the death of the light bulb. Anyone familiar with automotive electronics? He knows that it is assembled using parts that are radically different in their “margin of safety” from ordinary parts. Which are used in consumer electronics. Not in the sense of the mechanical strength of the parts themselves, but in the electronic potential reserve. Because of this, auto electronics are quite expensive and they are used specifically in cars. The use of simple parts in auto electronics leads to their rapid failure. In general, without delving into theory. Simple advice. While the car is cold and running at high speeds, there is no need to turn on the headlights. Wait a few minutes until the voltage on the on-board network is more or less stabilized, then turn on the headlights and only 10-20 seconds after that you can turn on the headlights. After a few more seconds, when the lamps have warmed up a little, you can go. Increase engine speed. By following this simple recommendation, it will be more difficult to spot a burnt-out light bulb in a headlight. If you analyze the burnout of lamps, they almost always burn out when turned on. During operation, they, as a rule, rarely burn out. I have been using this method for a long time and have almost no complaints about lamp burnouts in my various cars.

All fuel-injected cars have increased revs when cold, and the lights only light up on Logan and Largus cars. You should have installed a regular relay on the lights and there would have been no problems or theories about where these problems come from.

What do they give the relay, I wanted to ask? Is the theory still interesting? Both in the steering column contacts and in the relay contacts. Relays are installed in other cars - to save not the lamps, but the contacts of the expensive steering column switch from excessive load and decouple the power circuits (shorten them) and all that... Your point of view about the influence of an additional relay on the safety of the lamps is interesting. I have mileage and a considerable lifespan (more than 10 years) - but the factory lamps are still in place... Maybe I still have a German OSRAM and not a Muhosran one under license and import substitution? Lamps often burn out for those who work in start-stop mode (taxi drivers) - turn them off and start them, turn them on and off. And for those who drive on bumpy roads with poor surfaces with the lights on. Well, why does the relay-regulator drive 15.2 instead of 14.8 volts? I read about Logan 1.4 and remembered: everyone had different generators on Logans before. The 1.4 and 1.6 differed in both power and brand. For example, I have a 1.6 with air conditioning - Mitsubishi costs maximum power. And at 1, 4 there were low-power Valeo. Accordingly, the relay regulators are also different and calibrated differently. And on a low-power generator, voltage surges are larger.

I'll tell you a terrible secret. Light bulbs burn out everywhere, even on Ferraris. Therefore, you should not put Logans and Largus out of brackets. On my last Logan, not a single light bulb in the headlight burned out in 4 years, and on the current one, everything is intact for 3.5 years. Well, yes, I have running lights installed on both Logans, and expensive Philips lamps were installed from new. Perhaps this also somehow affects the situation? However, I always adhere to the basic rule of turning on the headlights. Described above.

Another interesting nuance... In the most common brands in Russia today, Kia Rio-Solaris, the low beam headlights are turned on automatically when the engine is started (without asking the driver). The lamps are the same H4. But not OSRAM, but something Korean-Chinese. And the lamps don’t light up - there’s no such problem. And all because there is a relay-regulator built into the generator - two-mode (from the load) and with temperature compensation from winter-summer! So the point is the old-fashioned design and low-cost logan type, and not the skill and experience of the driver... and the lack of a relay

Good afternoon, forum members! Allow me, so to speak, to “get smart” on the topic of light bulbs. (It just so happens that I have been working on the topic of “lamp protection” for more than 15 years). When cold light bulbs are turned on, the cold filament current is 10 times (or even more!) higher than the working current, which leads to the burning of the lamps. That is, the better the contact in the lamp base, the worse it is? More likely “yes” than “no”... What will graphite save you from? Maybe from overheating - it will improve heat transfer from the lamp to the base... How does a regular relay help against lamp burnout? - No way. It relieves the burden on the steering column switch, which is more expensive than the relay and the relay is easier to replace. How does an electronic relay (electronic units) help? For example, electronic relay DRL-30-MA? — Very strong: 1. It has a “soft start” - for BS lamps, or a “soft start” (switch on with current limitation) - for DS headlights. The relay has the ability to easily change settings. 2. In addition, this relay has voltage stabilization (limitation) at a specified upper level - by default (from the factory) it is set to 14.7V and can be very easily reconfigured. 3. This relay has a “DRL mode” - the headlights operate when the normal mode is turned off (i.e. all daylight hours!) in the “DRL mode” at 65% (2/3) - for BS or at 25% (1/4 ) - for DS (percentages can be changed). The DRL mode turns on after starting the engine and works until the ignition is turned off (of course, it is possible to control this mode - see Description of the relay). In DRL mode, i.e. reduced brightness-power, lamps can work for a very long time without losing their characteristics and properties - they specifically tested them on their machines for 5 years or more (compared with new ones). When turned on normally, 100% is supplied to the headlights (smoothly for low beam or sharply for high beam). The problem of lamp burnout was and is especially obvious on Chevrolet Lacetti, Chevrolet Captiva, GW Hover (these generally have voltage in the on-board network jumping to 16 volts or more when reverse gear is engaged!), etc., it was for them that the “” function was originally introduced. stabilization-limitation" voltage on the headlights. So, our cars are clearly not the leaders here.

A couple of years ago I set the BS and PTF to “soft ignition” without changing the lamps, although the low beam is always on when driving.

I know about soft ignition and how it works. Now we need to implement it. I'm tired of changing lamps. Although I don’t turn them on often.

Aliexpress sells a harness that breaks the standard wiring, with a relay switching power to the lamps directly from the battery, I’ve been using it for a year: the lamps do not burn out. On Largus, as on some Japanese cars, the lamps are powered without a relay, and the load goes through the steering column switch, and when driving it rattles, sparks and the contacts burn out, as a result the lamps and then the steering column switch burn. It's called - 1set - H4 headlight brighter headlight booster h4 headlights car headlight brighter There is a minus during installation, the H4 ceramic connectors on the harness are slightly larger than the standard ones, the headlight cover does not snap into place, I warmed up the bubbles on the cover with a hairdryer

I looked, it looks like ordinary relyushki. The circuit is used to relieve the load on the steering column contacts, and does not affect the service life of the lamps. Or is there a smooth increase in current here?

That's right, they just switch the power to the battery. First of all, the lamp needs stable power, when I turn it on they never burn out, only when driving, I suffered for six months with monthly replacement of lamps and bought such a harness (you can make it yourself), I’ve been driving with regular lighthouse lamps for a year now and no problems. The asking price is 600-700 rubles, you can find it cheaper there, I just paid more for the H4 ceramic forks

PTF lamp (fog lamp)

There is no access to the lamp from the engine compartment, so replacement is made from below.

Remove the fender liner by removing the screws;
Disconnect the block from the lamp by pressing the lock;
Remove the lamp by turning it a third of a turn counterclockwise.

Install the lamp in the reverse order.

Attention! In practice, replacing lamps in a Largus headlight is much easier. In other words, it is not at all necessary to remove the battery and fender liners (lockers). If you get the hang of it, you can access all the headlight bulbs from the engine compartment.

Let us remind you that other operating and repair instructions for Lada Largus are in this category. It is convenient to find the answer to your question based on the content.

We will show you how to replace the headlight bulb in the front headlight of a Lada Largus with your own hands. This is not the easiest task as it might seem at first glance; many people, when changing these lamps, remove the battery; we will show a method without dismantling it. This applies to the left headlight, where the battery is located; the right one will be simpler.

What do we need for work?

In order to replace the lamps in the headlights of the Lada Largus, we will need:

Torx key T-20;
clean cotton gloves;
replacement H4 bulbs.

Let's start replacing

We find the hatch for the high/low beam lamp. It is closed with a protective plastic cover. Press the latch and remove it.

Removing the protective cover

Under it we see a rubber boot, from the center of which protrudes the light bulb power connector. We remove it from the lamp by simply pulling it out.

Disconnecting the power supply

Now you can remove the boot itself.

In front of us is a light bulb, pressed with a spring clamp. We press our finger on the upper part of the lamp clamp and remove it from under the hook on the reflector.

Removing the spring clip

After this, simply fold the spring down, freeing the lamp.

If we accidentally touched the flask with our bare hands or simply got it dirty with something, we wipe it with a napkin soaked in alcohol.

On a note. Some craftsmen do without removing the fender liners, performing all manipulations from the engine compartment. But, firstly, for this you need to have the hands of a pianist, and secondly, when working with the left headlight, you will still have to remove the battery.

In order to climb through all these pipes, you need to have the hands of a pianist and remarkable patience

Cost of lamps

All of the above lamps can be purchased at almost any auto store. For example, a Philips H4 Premium +30 low beam lamp installed from the factory costs about 120-150 rubles. PTF lamp H11 Philips Eco Vision about 500-600 rubles per joke. All other lamps cost no more than 40-50 rubles.

Low beam bulbs on a Lada Largus car are a short-lived element, so sooner or later car owners will definitely have to deal with replacing them. For beginners, this task usually raises many questions. Therefore, below we will look at how to choose the right one and how to change the low beam bulb on Largus.

Choice

Currently on the market you can find such lamps from a variety of manufacturers, among which are the following:

In addition, domestic Mayak light bulbs have recently proven themselves to be quite good. Their advantages include not only low price, but good quality.

Of course, when choosing lamps you need to pay attention not only to the brand, but also to the following characteristics of the lighting element:

However, it should be noted that such light illuminates the road well only in dry weather. In fog or rain, ordinary lamps are preferable.

Thus, each driver can choose the most suitable light bulb, taking into account his own financial capabilities and the conditions in which the car will be operated.

Replacing the low beam lamp on a Lada Largus is carried out in the following order:

Next, you need to install a new light bulb in place. It is better to do this work with gloves so as not to touch the glass flask with your own hands. The fact is that traces of fat can lead to rapid burnout of the lamp.
Then you need to fix the base with a spring clip, put the block on the contacts and then install the plug in place.
At the end of the work, you should connect the battery and check the operation of the headlights.

This completes the replacement of the low beam lamp in Largus. As we can see, this operation is carried out extremely simply.

F9 - left headlight.
F10 - right headlight.

Often the cause of the malfunction is poor contacts of the fuse terminals. In this case, you just need to clean them.

Stop signal

The principle of replacement is similar to the installation of the above-mentioned lamps, but it has its own nuances. Here, first, the trunk lid is opened and its decorative panel is removed. So, in order to replace the brake light, you must first of all clear the approach to the wing nuts.

After removing them, the entire headlight is turned out, which would be very problematic to do on your own. After all, you need to bring out its upper and lower parts at the same time so that they do not become a surprise. After unscrewing the screws, access to the lamp is open. The failed part is replaced, and all the previously listed steps are performed in the reverse order.
