Now the headlights illuminate, rather than just shine. Replacing lamps + FAQ: How to adjust the headlights yourself!

The original headlights were not bad, but they weren’t satisfactory - they were rather weak.
We are used to better road lighting along Logan and Fiesta. And adjusting the headlights, two weeks ago, helped, but only slightly. Therefore, on Saturday new lamps were purchased and installed in the headlights.

Traditionally, this is Philips X-treem vision +100% H4 55/60W

Why these lamps

: at Fiesta and before that at the four, I tried almost the entire range of lamps from stores. So - no Osram Knight Breaker Plus, no PIAA, and even xenon installed instead of standard lamps, without blinds, does not shine so well!

By the way, the old dumps are quite good - Osram, made in Germany, but it felt like after installing the new lamps - they were as bright as a light bulb in the glove compartment!

Now you don’t have to strain when driving in the dark, a very even light, of a whitish tint, illuminates even the oncoming side of the road 25 meters ahead, and your own side of the road about 100 meters.

The photo on the brown fence is certainly not an indicator, but in general the lighting is better than the native osram, even here, 2 meters from the fence =)

Comparison of Philips X-treem vision with xenon instead of standard lamps:

These lamps were compared with “makeshift” xenon (that is, xenon installed instead of standard lamps, without special blinds) back at Fiesta - the illumination is approximately the same, but the xenon either shines strongly into the eyes of those oncoming - it illuminates a large area above the “tick”, or only shines 15 meters from the hood. Bright. But there’s no point - what’s the point of having headlights shining under your nose? Philips X-treem vision, when the headlights are adjusted correctly, illuminates much of the road without blinding oncoming traffic. On an unlit road, you can safely drive without turning on the driver at a speed of up to 90-100 km/h.

In general, if you do not have enough headlight light, I highly recommend Philips X-treem vision - this is the best choice. Moreover, in one of the most famous chains of auto stores (so that this blog is not considered an advertisement, I don’t write the name) they have a sale until November 30 - only 849 rubles. Usually they cost 1400-1700 rubles. ______________________________________________________________

Well, now what was promised - about how to adjust the headlights

(
on any car, not just Largus!
),

To make adjustments you will need a tape measure, a ruler, a chalk, a 5mm internal hexagon,

0) set the corrector to 0, no one should be in the car during adjustment! There shouldn't be a load either!

We choose a horizontal platform with a wall at the end, stand so that there is exactly 5 meters from the front of the car to the wall!
( L=5
meters on the diagram)

2)We measure the height A

. To do this, we look for a circle with a cross on the approximate center of the headlight, similar to a target, the size is approximately 1 mm in diameter. It is there, but not on all cars, if you haven’t found it, then turn on the low beam, put a dot in the place , (on the headlight the light is mirrored, relative to the wall, that is, the checkmark is down), that is, in the place where the light bends down from the horizon. And we measure the height A to this place.

We measure the same height A on the wall and draw a strictly horizontal
line 1
4)

Draw
line 2
strictly 5 cm below line 1 (If you have an angle α written under the hood α = 1% If it is more than 1% (sometimes it is 1.3, or even 1.5% - then you will have to calculate how much your % of 5 meters. And draw a line that much lower 2)

We set the horizontal part of the light to line 2, no higher, no lower. On Largus and Logan it is screw 4 (see picture below) - it is turned with an internal hexagon 5.

Using screw 7, we set the light so that the “checkmarks” are strictly opposite each headlight. It can be turned by hand or with an adjustable wrench.

Everyone, enjoy life! Everything seems complicated, but it actually takes 5 minutes!

I can say that the factory setting of the headlights was approximately 2% slope, and should have been adjusted by the dealer during pre-sale preparation.

How to adjust headlights on Lada Largus

It should be admitted that adjusting the headlights on Largus is considered a scrupulous and slightly tedious procedure. But, despite this, it is extremely necessary, since the safety of the car owner and his passengers depends on how well the lighting is set up. If, while driving, drivers of other vehicles signal by flashing their head optics, thus indicating that they are being blinded, then adjustment of the headlights is simply inevitable.

On the road you need to respect not only yourself, but also other road users.

How to legally install LED bulbs in headlights?

According to the law, if you make changes to the design of the car, then you have the right to operate the car on public roads only after going through a certain procedure in legalizing the installed equipment in the traffic police and in specialized organizations.

We discussed in more detail how to formalize the conversion of a car in the article “Fine for gas equipment in a car.” Let us recall that in this article we examined the process of legalizing the installation of gas equipment on a vehicle.

When installing LED lamps in a car, you will first need to re-equip the headlights in a specialized organization, which will install the appropriate lenses and other equipment in them that will provide the LED lighting with an optimal beam of light projected onto the road.

Also, to legally register LED optics, you need to obtain permission to re-equip the car.

In particular, after installing / altering the headlights in a specialized organization, you must register the re-equipment of the car with the State Traffic Safety Inspectorate and obtain a certificate of compliance of the vehicle with the changes made to its design in accordance with safety requirements.

Read more about the process itself here.

Causes of malfunction of car optical devices

Before you start adjusting the headlights, you should make sure that this is the cause of all the problems. The vehicle must be checked for serviceability, since the correct direction of the light is directly related to the following components:

differences in tire sizes and tire pressures;
condition of shock absorbers;
uniform distribution of the load on all parts of the body.

If at least one of them performs poorly, the angle of illumination can be dramatically changed. If there are no such faults, then you can begin adjusting the lighting.

Conclusion

People who often operate their vehicle at night must adhere to the basic rules for adjusting headlights. This is done so that this seemingly insignificant detail does not become the cause of a serious accident.

In the category “Adjusting the headlight angle” for Lada Largus, the original spare part number is located in the catalog of the manufacturer of your vehicle. Selection of this part is possible only by the VIN code of the vehicle. To order a part or find out its article number, you must:

1. Create a request using the vehicle's VIN code

2. Contact our operators - contacts

Specialists will select numbers of original spare parts and analogues that are present in our range, advise and help formulate an order and delivery.

Use spare parts catalogs to find and view information, photos of appearance or diagrams of other parts of Lada Largus cars.

The procedure for adjusting the headlights of Lada Largus

This procedure can be carried out by the car owner independently or by contacting service center specialists. Moreover, it is almost the same on all modifications of such a vehicle. It is carried out both on a completely new car and on one that has already been driven for more than one year.

Preliminary data fixation

Before starting this diagnostic step, the driver should prepare a tool box, a spare tire, and a full tank of fuel. The car is placed on a horizontal surface, and the smoother it is, the more accurate the indicators of the current state of the headlights will be. In addition to this, the engine remains idling and the handbrake is fully depressed.

An artificial wall is installed in front of the car, the height of which is 1.8–2.0 m. Moreover, the distance showing how any headlight on Largus works should not exceed 2.8–3.2 m. It is worth noting that such a visual barrier can make it yourself from chipboard or similar materials.

This scheme is suitable not only for Largus, but also for other cars

A load weighing 55–70 kg is placed on the driver’s seat. This helps align the lighting line. After this, the distance between the headlights, their height above the road is measured and the average value between them is found. All this is transferred to the wall using chalk, ultimately representing a dot projection with marked edges and centers of the headlights.

The actual adjustment

To start adjusting the lighting, you need to create pressure in the chair, that is, either sit on the seat or put additional weight there. At the same time, slight rocking of the car will help remove vibrations from the body and shock absorbers.

The regulator is moved to a position oriented towards one person. This is precisely why the load was placed on the driver's seat. Then the low beam is turned on and the output is carefully examined with the actual deflection of each headlight beam.

Under the hood there are regulators that allow you to use a screwdriver to level the output of the light beams. They must fully correspond to the points displayed on the artificial wall, both vertically and horizontally.

Checking the correction made

All optics, like each individual headlight of the Lada Largus, are considered adjusted if its rays go directly to their wall projections. Fixing the adjustment and checking the work done is carried out through a test drive. The main thing here is that the light beams of car headlights did not blind other road users.

Reasons for poor lighting even after adjusting the headlights

Cloudiness of the plastic shell results in poor light dispersion. There are two solutions here - buying new optical elements or polishing, which, by the way, you can even do yourself. For this purpose, a grinding machine is used, during breaks in which the plastic is washed to the desired level of transparency.
The characteristics of headlights also affect the quality of illumination, since some are equipped with more powerful bulbs, while others have less. In this case, some use xenon “support”, which provides the proper luminous flux with minimal power.
Cracks in glass can cause light to refract incorrectly. Here either its “reanimation” or complete replacement should help. In any case, this is one of the most expensive repairs, so it is better to periodically check the glass for mechanical damage.

Headlights for Lada Largus - main characteristics and tuning

A modern car is equipped with a large number of light sources. Some are used to indicate the dimensions of a car, others are used to notify traffic participants of the intention to perform a particular maneuver, and to give signals. There are rear and front lights installed on the right and left corners of the body. Among them, the main ones are those that are responsible for illuminating the road at night.

Headlights perform an important function: they illuminate the space in front of the car and make it visible to other road users. They should not be so bright that they blind oncoming traffic. It is important that the headlights are always in working order, because without quality lighting it is dangerous to move in bad weather and at night. If the headlights are faulty, the driver may not see an obstacle on the road, and the consequences will be disastrous.

Lamps for foglights - delivery of parts to VAZ

You can order Largus fog lamps from us with delivery in Moscow and the region. The PTF uses a lamp with an H11 12v 55w socket. Depending on the purpose, you can install lamps on Largus cars:

Regular halogen.
With increased light output.
Under xenon.
LED.

On Largus, the PTF is equipped with Philips Eco Vision lighting elements with an increased service life. It is possible to install Philips or Osram elements with increased light output; they will illuminate the roadway more efficiently. If a car owner wants to get the xenon effect, it is necessary to install electric lamps with a blue bulb, which will create a bright white light with a glow temperature of 4500-5000 K. To adapt foglights as an alternative to DRLs (this is real and quite possible), LED electric lamps should be installed. They will not be able to completely illuminate the road space, but as an alternative to running lights, they are what is needed. If you find it difficult to choose a product yourself, contact the professionals of our company. The specialist will place the order and, if possible, provide a discount.

Main characteristics of standard Largus head optics

During the development and production of the Lada Largus, the engine and headlights were borrowed from Renault Logan. The standard headlights are equipped with standard AvtoVAZ halogen lamps (H4 base) with two filaments. They are chosen as light sources due to their durability, optimal light output and the fact that they do not darken over time. A standard Largus lamp with a power of 60/55 W (high and low beam, respectively) produces a luminous flux of at least 1500 lm.

The Lada Largus optics use a standard fixed diffuser, with the help of which the direction of the light flux is adjusted by the position of the reflector and the lamp. The adjustment screws are hidden in the engine compartment, thereby protecting them from dirt and moisture. The headlights can be adjusted from inside the cabin using a hydraulic adjuster, but if precise adjustment is needed, this is not enough.

Headlight malfunctions and how to fix them

There are not many items on the list of headlight headlight breakdowns. This is mainly due to damage to the lantern glass, failure of the corrector or the lamp itself. If the Lada Largus low beam lamp and corrector can be replaced, then the glass is installed only with the headlight assembly. Largus optics do not cause any inconvenience to owners. The most common problem is low beam bulbs burning out.

You can choose and install a good headlight bulb yourself. On the market of automobile spare parts and accessories there are light bulbs from both domestic and foreign manufacturers. Chinese lamps are not of very high quality: they burn out quickly and do not provide sufficient visibility on the road.

Standard halogen light should be yellowish. Many people prefer the so-called pseudo-xenon, which makes the glow white, but in bad weather conditions such lamps are inferior to standard ones. The latter sometimes even outperform LED and xenon optics, which produce a powerful luminous flux, but cost a lot of money and are installed in specialized centers. In fog and rain, halogen lamps demonstrate the highest penetrating ability of the light beam, which ensures their leading position.

Replacing lamps

The operation of replacing the lamp is simple and even beginners can do it. It is carried out as follows:

The negative terminal is disconnected from the battery.
A slight turn removes the plug from the back of the headlight.
The wire block is disconnected from the lamp.
The latch is removed from the grooves by pressing it with your finger.

The failed lamp is removed and a new one is installed in its place. It is recommended to use gloves when working, as fingerprints on the flask can lead to its premature burnout. The lamp is attached using a latch, a block with wires is connected to it, and a plug is put in place. A terminal is connected to the battery, then the operation of the headlight is checked.

It is recommended to change the bulbs in both headlights at once. This way you will be able to avoid the failure of another light bulb at the wrong time and ensure a uniform glow.

The problem due to which the Lada Largus headlight does not light may not be in the lamps. If replacing them does not bring any results, the fuse may have blown. The mounting block is located in the cabin at the bottom left of the steering column. Replacing fuses is a matter of seconds. Two fuses are responsible for the light. Even if they look intact, the cause of the malfunction may be hidden in poor contact. There is no special relay for headlights in Largus, and therefore the source of the problem may be oxidation of the contacts of the headlight itself.

There are often situations when the headlights do not work due to poor ground contact. In this case, inspection and cleaning of the contact is necessary. If this does not help, contact the service center specialists to identify the causes of the malfunction and eliminate them.

To replace the low/high beam bulbs, you do not need to dismantle the entire headlight or any of its parts, so the process does not take much time. If the headlights are shining, but the light beam is incorrect, the reason is a faulty corrector. Its main task is to lower or raise the luminous flux depending on the location of the car body. If the vehicle is loaded, then without adjustment by the corrector the light will blind oncoming traffic. This part cannot be repaired, which means it is immediately replaced with a new one. This will require disassembling the headlight unit.

How to replace the lamp?

Replacing a low beam lamp in a LADA Largus is not a complex procedure, which is quite feasible for inexperienced owners. Here you will need a simple set of tools. The right headlight will cause some difficulties, since the battery is located nearby. In general, this point can be easily eliminated. We will tell you how to change the lamp.

The lamp responsible for low beam in the Lada Largus has a rubber protective cover. This element can be easily moved to the side using manual force. This is done simultaneously with the removal of the power supply wire block.

The sequence of actions is as follows:

We turn off the power to the on-board network by removing the terminals from the battery or turning the switch, which is structurally present in the Lada Largus. This mandatory action implies ensuring electrical safety during the full range of manipulations.
We remove the rubber pad that covers the electrical component.
Now carefully move aside the pair of metal antennae that hold the lamp in the socket.
We disconnect the cable plugs with which the lamp is connected to the on-board network.
We mount the new lamp in the designated socket and securely fix it.
We connect the cable block to the electrical network.
Finally, we return the rubber protective plug to its original place.
We install all other previously removed components in their original places. Now you know how to change lamps.

Upon completion of the entire list of manipulations, we are sure to check the correct functioning of the entire set of lighting fixtures, including if the bulb dimensions were replaced.

Important! If suddenly, when checking, the lamps began to emit a dim luminous flux, or the side lights switched to flashing mode, then this indicates insufficient contact with the body. The reasons may include both dirt and ordinary oxidation, and it is not always necessary to replace the size bulb

Replacing the headlight

It may be necessary to replace standard optics in rare cases. Usually the headlight is removed if you need to replace it with a new one, or during tuning. The process is quite simple, the only problem is that you need to remove the front bumper, since without this you cannot get to the lower mounting screws. The procedure for replacing a Largus headlight is as follows:

The car is placed on a level surface and secured with a parking brake.
The negative terminal is disconnected from the battery.
The front bumper is removed.
Bolts 1,3 and 4 (photo) are unscrewed, thereby releasing the headlight from the mount.

Headlight mounting screws

The cover is removed and the wiring block is disconnected from the lamp.
The headlight range control is removed.
The marker lamp holder is removed.
The headlight unit is released and can be removed.

New optics are installed in the reverse order, the gaps between all contacting parts should be minimal. After replacement, the headlights must be adjusted.

Penalty for installing LEDs in headlights in Russia in 2020

Also, do not forget about such a disadvantage as legislative restrictions on the installation of such diode lamps in headlights intended for halogens (or unauthorized installation of headlights in cars that also have LEDs installed on similar models).

photo: autoevolution.com

In this case, there is a violation of paragraph 3.1 of the list of faults and conditions under which the operation of vehicles is prohibited:

In short, in 2022, after the published resolution of the Plenum of the Supreme Court of the Russian Federation No. 20 of June 25, 2022, in most cases the punishment for a driver using LEDs in headlights is a fine of 500 rubles. Deprivation of rights is imposed only if light bulbs are installed in which both the color of the lights and the operating mode do not meet the requirements.

Headlight adjustment

Car owners know that the procedure for adjusting Largus headlights with your own hands is not the fastest and easiest process. But it is extremely important, since the safety of those in the cabin depends on the correct setting of the light. The fact that there is a need to adjust the lighting of the head optics may be indicated by the signals of oncoming cars: they will flash their high beams, indicating that you are blinding them.

Before you start setting up, you need to make sure that it is necessary. The correct light is ensured by the following conditions:

good condition of shock absorbers;
optimal tire size and pressure;
uniform distribution of load on different parts of the body.

If these criteria are deviated, the glow angle will be incorrect. If the problems described above are not identified, then you can safely move on to adjusting the light.

Let's sum it up

PTFs are quite useful devices that help the driver move confidently in difficult weather conditions. As you can see, not all Lada Largus configurations initially have such lighting devices in their arsenal. For caring owners, this is not an obstacle, and they easily purchase and install PTF in their cars.

We examined two options for installing lighting equipment in LADA Largus and found that they are quite simple. If your station wagon does not yet have these useful products, then feel free to purchase them and install them, after which the bad weather will not be able to scare you.

Headlight adjustment algorithm

To adjust the Lada Largus headlights, you can either contact a service center or do it yourself. The main feature of this procedure is that the model of the vehicle, its modification and equipment does not matter. The adjustment is carried out the same way on both new cars and used cars.

Data capture

This stage is diagnostic; before starting it, you need to prepare the tools, install the spare wheel in its original place, and fill the tank full. After this, the car is placed on a flat horizontal surface. The accuracy of the performance indicators of the head optics will depend on how flat the plane is. Additionally, the car must be started and idling. The car should be secured with a parking brake.

Replacing the hydraulic corrector with a similar device

In order to replace the hydraulic corrector for headlights on a VAZ 2110, you need to stock up on a wrench with a 21 and half hour head. The actions are performed in this order:

The adjustment knob is removed (you need to pull it) on the dashboard. Under it there will be a nut 21, which should be unscrewed. This releases the master cylinder and can be removed.
We open the hood and find headlights and working hydraulic mechanisms installed on top. On each one you need to release the latches, turn the cylinders counterclockwise and remove them.
Disconnect the tubes (most often they are secured with clamps with a screw clamp). Now all the elements of the system located under the hood need to be brought into the cabin through an opening closed with a pliable seal.
Install all elements of the new Lada Granta hydrocorrector. The sequence is reversed.

Tuning Largus headlights

Many Lada Largus owners are dissatisfied with its appearance. Although the designers have created a new look, which is strikingly different from previous VAZ models, it is still not original. Largus owners are offered kits for upgrading optics, varying in quality and price.

Instead of standard optics, it is possible to install a more powerful lensed one. It can perform two functions at once: it increases driving safety at night and makes the car more attractive. In some Largus configurations, fog lights (FTL) are also installed at the manufacturer's factory.

You can install not only xenon, but also bi-xenon, when low and high beam are combined in one lamp. At the same time, it is not necessary to buy new headlights: xenon is easy to install in standard optics. The on-board computer may resist such modifications; in such cases, so-called “decoys” will help.

Xenon is installed not only in conventional headlights, but also in lenses. You can add “angel eyes” - a signature feature of the exterior of BMW cars. Stores offer block headlights with daytime running lights or additional lights for Lada Largus, which can be installed in their original place without any modifications.

Replacing optics on Largus is an expensive procedure even when installing standard equipment, not to mention lenses or xenon. For this reason, it is recommended to carefully monitor the condition of the headlights and avoid possible mechanical damage in every possible way. It is recommended to use a car in the dark (this is especially true in winter) only if there are properly adjusted lights. This is necessary to ensure that insufficient lighting does not cause a serious accident and threaten the health and life of all passengers.

How to choose lamps

It is worth distinguishing between the four lamps that are located in the Priora headlight unit - low and high beams, turn signal and dimensions. It is the low beam lighting that should interest you. It is equipped with an H7 lamp. All lighting is represented by halogen optics.

In some cases, when it becomes necessary to replace optics, drivers decide to install alternative options, but maintaining factory standards will still be a more reliable choice.

As for the pricing policy, a low beam lamp will cost 250-500 rubles on average.

The characteristics of various halogen lamps may differ from each other; you should pay particular attention to the parameters that correspond to low-beam lighting devices. All necessary parameters and certificates must be publicly available on the packaging. The luminous flux, for example, is limited by the state standard and must correspond to the range of 1350-1650 lumens. If the specification is unsuitable or there is no information about it, do not purchase such products.

Adjusting the direction of light of the main (low, high) and fog lights

See also: Adjusting headlights with a corrector (depending on load)

For adjustment you will need: a 5" (or 6") hex key and a Phillips screwdriver.

Note: Check and adjust the headlights with the vehicle equipped (with a fully filled tank, tools and spare tire).

1. Pre-check and, if necessary, adjust the tire pressure to normal. (see here)

2. Place the car against a wall, at a distance of 3 m (for example, in a garage). Place an additional 75 kg weight on the driver's seat, thereby simulating the driver's weight. Mark the screen on the wall as shown in the figure. The longitudinal plane of symmetry of the car should pass along line 0 on the screen. Rock the car laterally so that the suspension springs self-align.

3. Measure the distance from the center of the headlights to the floor on your vehicle. This will be the distance h on the screen.

4. Set the headlight level control (if installed) on the instrument panel to a position that corresponds to the load of a single-driver vehicle. (see here)

5. Turn on low beam.

6. It is recommended to check the direction of the light spot for each headlight separately. Cover the second headlight with opaque material during adjustment.

7. If the location of the light spots does not match the picture, open the hood. By rotating the adjusting screw (view of the left headlight from the engine compartment), adjust the horizontal position of the light spot on the screen...

8. ...and vertically.

To rotate the vertical adjustment screw, insert the hexagon through the hole in the upper cross member of the radiator frame.

This is where the screw for adjusting the headlights vertically is located.

9. The headlights are considered adjusted when the upper boundaries of the left parts of the light spots coincide with line 4, and the vertical lines 1 and 2 pass through the intersection points E1 and E2 of the horizontal and inclined sections of the light spots.

10. If necessary, adjust the second headlight in the same way.

Adjusting the fog lights

1. The light beams of the fog lights are adjustable only in height. For access to the adjusting screws on the fog lamp housings, holes are provided in the fog lamp trims. By rotating the adjusting screws with a Phillips screwdriver, ensure that the upper boundaries of the light spots are on line 4 or slightly below it.

This is where the adjusting screw A is located on the fog lamp housing and the hole B for adjustment in the headlight trim (view with the fender liner removed).

What is a hydraulic corrector and how does it work?

The hydraulic headlight corrector is installed on the Grant from the factory. This device adjusts the headlights higher or lower depending on the vehicle's load.

You need to adjust it yourself - there is no automatic setting.

The corrector control is located under the light switch handle. Position 0 corresponds to a car with one person - the driver.

Principle of operation:

the handle controls the hydraulic corrector cylinder;
the cylinder regulates the pressure in the flexible tubes that go to the pushers;
pushers are installed in the headlights - the higher the pressure in the tubes, the stronger the liquid inside the pusher presses on the rod;
the position of the rod deeper/further is responsible for adjusting the headlight higher/lower.

The operating principle of the hydraulic corrector is clearly shown below:

Visual representation of the headlight hydraulic adjustment system

What to do if the hydraulic corrector is broken

Have both or one headlight stopped responding to the hydraulic corrector? Most likely your pusher is broken .

If you want to fix the pusher, there are two ways .

Table 1 . Options for repairing the headlight range control pusher.

Option 1 – barbaric.

No further adjustment.

We remove the faulty pusher from the headlight;
After warming the tube for elasticity, remove the pusher from it;
From the side of the tube we twist the self-tapping screw at an angle - the deeper, the more the rod will stick out;
We adjust the length of the screw until the desired result is obtained.

Option 2 – humane . We return the corrector to full working condition.

We remove the faulty pusher from the headlight;
We warm the tube and carefully remove it from the pusher;
We try to move the rod with pliers - the pusher does not work if there is little liquid in it and there is no required pressure;
If the rod moves, use a syringe with a needle to pump antifreeze into the pusher and put the system back together.
The rod does not move - pump a small amount of antifreeze into the pusher with a syringe, try to develop the rod. Add antifreeze to the desired level.
The optimal fluid level in the pusher is determined experimentally or by comparison with a working corrector.

Link to a detailed description of the second method with comments here.

A corrector kit costs about 700 rubles - it may be easier to replace it

Adjusting headlights with a corrector in the interior of Lada Largus / Lada Largus

See also Instrumental adjustment of main and fog lights

Note: If the headlight range control does not work, and one of the headlights begins to shine too much downwards, then check whether the adjustment cable has come off the headlight range control. To do this, remove the rubber boot from the corrector on the headlight and insert the cable into place (see picture here)

Turn knob 1 down to make the headlights shine lower, or up to raise the beam of light.

Basic position: car with empty trunk, one driver or driver and one passenger in the front seat.
1, 2, 3 passengers and luggage not loaded.	1
3 passengers and trunk loaded.	2
One driver and the trunk is fully loaded.	3

The regulator is located on the left side of the panel. Adjust the low beam height. There are three numbers on the regulator: “0, 1, 2, (3)”. Turn the control knob from 0 to 2 (or 3) one by one and the low beam will gradually lower. Try to turn the knob at one minute intervals. If the regulator is returned too quickly, the electrical regulator may malfunction.

Addition (experience of forum members)

When driving around at night with an oncoming car, I often think that 50% of our drivers do not know and do not know how to use headlight range control. I myself use it very often, and what I like about Largus is that the corrector does not have fixed positions. On cars with fixed corrector positions, the adjustment step is often too large. On Largus you can very accurately adjust the position of the headlights.

How often do you use a headlight corrector, and what criteria do you use to set it?

Where there is a corrector: Outside the city, I put it in the upper position in order to increase the illumination. When fully loaded, I lower it down. In the city I set it as low as possible, there is enough street lighting, headlights in the city are more needed to indicate a car on the road than to illuminate the path. Where there is no corrector, there is no need to adjust anything. On the highway, it's mostly unadjusted headlights, lovers of pseudo-xenon with non-standard lamps and xenon installed in unsuitable optics that hurt your eyes.

Preparing to make adjustments

To achieve the correct position of the headlights, the adjustment procedure must be performed under certain conditions. Carry out the following preparatory work:

Find a flat area without a slope adjacent to a vertical wall. One of the suitable options is a concreted entrance to the garage; the role of the setting template will be played by the gate.
Remove unnecessary items from the trunk and interior of the car, leaving only the factory tool kit, first aid kit and spare tire. The goal is to ensure the curb weight of the vehicle specified in the operating instructions.
Check the pressure in all tires and adjust them to normal if necessary.
Clean the optical glass from dust and other contaminants that block the path of light flow. Do not use solvents, only ethyl alcohol-based glass cleaners.
It is advisable to fill the fuel tank full, fill the washer tanks to the top and, if necessary, add antifreeze to the expansion tank.

A headlight adjustment diagram is drawn on the garage door or wall adjacent to the site. You will need a tape measure, a long straight bar and a marker. The color depends on the chosen background - for a white wall it is better to take a black felt-tip pen, for a dark gate - chalk. The diagram is drawn as follows:

Drive the machine close to the wall. Using body parts or the car brand emblem as a guide, mark a point on the surface that coincides with the central (longitudinal) axis of the vehicle.
Measure 7 m from the gate and drive the car to the specified distance. Draw a vertical line through the marked point.
Take 4 measurements on the car: from both headlight bulbs to the ground and to the center of the car. On models equipped with separate high and low beam optics, the listed measurements are made for all four bulbs separately.
Subtract 50 mm from the number indicating the distance to the ground. Set this size aside on the wall and draw a horizontal line.
From the vertical axis, plot the distances to the centers of the lamps along the drawn line. Place marks in the form of segments. The scheme is ready.

Before adjusting the position of the optics, it is also recommended to treat the adjustment screws with a penetrating aerosol lubricant such as WD-40, since the connection threads could become soured due to extremely rare rotation. As a rule, the adjusting screws are located on the rear plane of the headlight housing, facing into the engine compartment. The shape of the head is for a Phillips screwdriver, hexagon or special key.
