Electrical diagram of the LADA Priora car

Difficulties with replacement

The most convenient thing is to replace the turn indicators. In other cases, you have to twist very tightly and stand in this uncomfortable position for a couple of minutes until the job is done. This is not very convenient, because the light bulb is a consumable, but the engineers could make sure that replacing it was as easy as the plastic steering wheel insert on the “ten”.

Another inconvenience is that you have to remove the battery. Nobody argues that it is better to turn off everything before starting work. But the battery is removed for reasons of rationality - the battery takes up a lot of space and interferes with working with your hands while you stand in an awkward position.

Why the headlights don't light up - reasons

The most common reason for headlights not working is a burnt out light bulb. Its service life is indicated in hours on the packaging. For a low beam bulb, this limit can be 400 hours of operation. The second extremely possible reason could be a wiring malfunction due to water leakage, or the wire simply frayed. This problem is already more serious, because you will have to fuss with it much longer than with a regular replacement of consumables.

Often, car enthusiasts are too lazy to change light bulbs, driving out onto the road in “one-eyed” cars. This is very unsafe - it is recommended that immediately after a malfunction is noticed, you go for a spare part to replace a new lamp.

Replacing the lamp in the high beam optics on a LADA Priora (VAZ 2170) car, although not difficult, is quite a sensitive matter. With the right approach, it is quite accessible to anyone. Therefore, let’s consider what base is used for the light bulbs in the headlights of this car, which models and manufacturers of light sources are most popular on the market, what are the differences and features on the pre-restyling and restyled versions, as well as what basic steps the step-by-step instructions for updating a burnt-out light bulb include.

Dorestyling

The life of the owners of pre-restyling cars was darkened by the fact that, in addition to the reduced service life, even then it was darkened by the fact that when replacing some light bulbs it was necessary to remove the socket along with the bulb - this, for example, happened when the owner wanted to replace a side light bulb. Owning a Priora became increasingly expensive; rarely did anyone think about buying another headlight - developed by other companies. Installing light bulbs from foreign manufacturers solved the problem of poor lighting well and for a long time.

Designations

• Low beam, for example, is marked 55H7, where 55 is the power in Watts, and H7 is the designation of the base;
• The main beam is designated 55N15;
• turn signal – 21PY21W;
• side light – 5W5W.

The lamps are in the headlights in a single unit, and the headlight unit is not always replaced - only the bulbs are changed. And not in vain - the factory headlight produces a cloudy light . Prior owners try to install the best lamps so that the headlights shine longer.

Replacing lamps in Priora taillights

Replacing the rear light bulbs is complicated by the fact that the combination unit inside supports the operation of the parking lights and brake signal. But it all starts just as simply, when replacing the bulbs in the rear headlights of the Priors, as well as the front ones:

• Remove part of the upholstery opposite the headlights;
• Unscrew the screws that support the protective housing of the rear light. In Kalina, there were nuts in place of the screws, and unscrewing them was another pleasure - they fell into a huge gap and were lost in the car body forever;
• Turn the brake light and clearance holders counterclockwise. Do not remove the socket, take it out together with the light bulb;
• It is easy to press down the lamp, turn it clockwise and remove it from the socket with a slight movement (it will almost fall out on its own);
• Carry out the operation in reverse order.

All you have to do is remember about the combination headlight - remember where each lamp was located, so that you don’t confuse anything during installation. With the rest of the light bulbs, everything is different - in addition to the ground (black wire ), wires from the ECU are connected to them. Thus, the “foglights” correspond to the red wire color, the turn signal indicator – blue, the green light is assigned to the reverse lamp.

Which wire goes where?

First, let's look at the back of the instrument panel. At the top there are:

• fuel level indicator;
• dashboard lighting lamps;
• control of right and left turns (separately);
• tachometer;
• block with many plugs;
• coolant temperature gauge.

As you can see, there is really nothing particularly complicated here. At the bottom of the instrument panel on the back side there are controllers:

• high beam;
• "emergency lights";
• CHECK ENGINE;
• battery charge;
• parking brake;
• oil pressure;
• air damper (for models with a carburetor);
• outdoor lighting work.

In addition, there is also a speedometer and a brake fluid level indicator lamp.

Now let's take a closer look at the pads. There are two of them - white and red. In the first, the connectors and wires look like this (in order):

1. Ground wire black.
2. Red-brown – low-voltage supply from the ECU to the tachometer.
3. Yellow – high-voltage supply to the tachometer from the coil.
4. Red-blue - comes from the battery through the 6th fuse Const with a voltage of 12 volts.
5. Green-white - leads to the coolant temperature sensor.
6. Green-yellow – fuse F1, responsible for the side lights.
7. This connector has no color, it goes to the throttle valve.
8. Red and white – leading to the CHECK ENGINE indicator light.
9. 2 orange wires leading to two F19 + 12 volt power fuses.
10. Same as the previous connector.
11. 2 blue-brown wires leading to the “VK” terminal of the handbrake.
12. The output to terminal D of the generator is a brown-white wire.
13. Gray and blue - wire going to the oil pressure sensor.

Layout of the restyled version

in Priora after restyling - small details invisible to the eye, the center console, the dashboard. The headlights have also changed - they have become quite a bit larger. The principle of their design has remained virtually unchanged, except that there is now one plug at the back to isolate the contacts.

The design of the headlamp unit has become more complex: now in place of the usual high beam lamp there is a light consumable, combined with daytime running lights, which switches between operating modes. PTF fog light bulb, everything is also mounted depending on the configuration.

Manufacturers and prices of analogues

The following options can be considered as analogues of daytime running lights for Priora:

• DRL-Une is distinguished by the fact that the unit can duplicate turn signals. Additionally, it has surge protection installed inside. These are white LEDs that produce up to 6 lm with a power of 0.02 W.
• Tuning “Angel Eyes”. The principle is similar - you can duplicate the turn signals. Only often this is not a self-assembled headlamp, but a product from the manufacturer. In it, each block seems to be “illuminated” by an LED strip along the contour.
• Eagle Eye LEDs. A very simple and inexpensive way. To do this, you just have to drill holes in the bumper to put LEDs inside, which together create a load of 12-15 W.

LADA Priora lamp base

Regardless of the year of manufacture of the Lada Priora, three types of lamps are traditionally used in the head optical system:

• Low beam.
• Long-distance lighting.
• Side lights.
  Read also:  Lada Vesta life hacks. 10 facts about the new Lada Vesta.

However, regarding the category under consideration (high beam), copies released before 2013 and after were equipped with different types of lamps:

• Pre-styling - H1 55W.
• Restyled – H15 55W.

With the same power of 55 watts and a single-filament structure, the type of base has changed from H1 to H15 (the DRL function has been added). At the same time, the modification of the light generator remained the same - halogen. In addition, the changes affected the design of the headlamp itself, which is clearly shown in the following images:

Note! Halogen lamps that are part of the Lada Priora lighting system should not be touched with unprotected, clean cotton gloves. Traces of grease and dirt left behind will lead to their rapid failure. To remove existing deposits from the surface of the glass, you can use a cotton swab soaked in alcohol.

Lighting repair

In some cases, owners need to disassemble and repair the headlight due to a malfunction of its components, to replace glass, with regular formation of condensation, or for tuning:

• We dismantle the lantern.
• The headlight unit consists of two parts connected with glue or sealant. Use a hairdryer to heat the joint around the circumference until the glue becomes softer.
• Separate the glued parts from each other with a screwdriver, cutting the glue with a mounting knife and continuing heating. On Bosch headlights, remove the four latches.
• We clean the disassembled parts from glue with a mounting knife and sandpaper.
• Upon completion of the repair, glue the separated parts together with sealant.

Then you need to wrap the headlight with plastic film and tape and leave until the sealant polymerizes.

Pre-styling Lada Priora

Adjusting the lights

Properly adjusted headlights are the key to safe driving at night. Good road lighting helps you avoid an obstacle, a pothole, or an open hatch in time, notice a pedestrian in a timely manner, and avoid a collision with a vehicle parked incorrectly on the side of the road.

Factory adjustment minimizes the harm caused by bright lights to oncoming drivers. After replacing lighting fixtures or body repairs, situations arise when they need to be adjusted. If you have the tools and a suitable place, it is not difficult to do it yourself.

• flat surface (opposite a wall, garage or gate);
• five-meter tape measure;
• a sheet of thick paper that does not allow light to pass through;
• hex wrench.

A diagram is drawn on a vertical surface that acts as a screen. At the level of the center of the headlights, draw a horizontal line. We put the parallel line 65 mm lower. We apply vertical marks opposite the centers of the right and left lamps, as well as in the middle, at an equal distance from them. We bring the car into equipped condition (there is no excess cargo, the tank is filled). We bring the tire pressure level to the nominal value. Further:

• We place the car 5 meters from the screen, the centers of the headlights are located opposite the corresponding vertical marks.
• We set the electric corrector drive for the lights to “0”, which corresponds to the minimum vehicle load.
• We load the driver's seat with a load of 75 kg and rock the car to install the suspension.
• Open the hood, turn on the low beam, and use paper to block the light from the right light fixture.
• Using the left headlight adjustment screw, using a hex wrench, adjust the horizontal border of the light to the bottom mark.
• We bring the bend of the light border to a vertical mark corresponding to the center of the lantern.
• We set the right headlight in the same way.

Signs and causes of headlight malfunctions, ways to eliminate them

The main reason for replacing optics is the cessation of performing its functions - reliable road lighting - or failure:

• the headlight fogs up, ventilation is impaired;
• deep cracks or chips in the glass;
• reflectors are faulty;
• electrical connectors are faulty;
• fastening elements are broken.

Replacing faulty elements allows you to restore the original properties of the lighting device, increasing the degree of driving safety for both the driver and other road users.

The headlights on the Lada Priora have a non-separable design. To change glass, a faulty element, or carry out tuning, you have to either replace the headlight with a new one, or, showing ingenuity, disassemble the standard one. Tools for dismantling and repair:

• cross-head screwdriver;
• key to “10”;
• industrial dryer;
• mounting knife;
• fine-grain sandpaper;
• scotch;
• polyethylene film;
• sealant.

Headlights play a significant role in car design. In case of repair, tuning or replacement with an identical analogue, it is necessary to indicate the procedure for dismantling and subsequent installation. To replace the headlights, you will need a 10mm wrench and a Phillips screwdriver. Step-by-step instruction:

• Disconnect the negative terminal from the battery.
• Remove the front bumper.
• Disconnect the connector with the wires from the headlight by releasing the latch.
• Unscrew the lower front bolt and the side screw of the headlight.
• Unscrew the screws and remove the casing.
• Unscrew the upper mounting bolt.
• We remove the headlight.

LADA Priora - bulb replacement

Replacement of low beam light , LADA Priora.

• Installation of xenon and LED lamps requires the installation of ignition units, and also contains a number of other features. Which low beam lamp is on the Ford Focus 2: which one is better to choose, article number, type, diodes Well-maintained and well-equipped optics. Replacing a low beam lamp on a Renault Logan: photos and. In particular, LED bulbs require the installation of a large reflector and a cooling system. Therefore, it will not be possible to do the installation yourself;
• The lamp ignites gradually, so the low beam turns on with some delay.

Advice! To avoid problems when driving in bad weather under the light of xenon or LED lamps, you should install fog lights with halogen lighting elements.

For these reasons, the low beam lamp on the LADA Priora is selected individually, depending on the financial capabilities of the car owner, the region and the weather in which the car is most often planned to be used. The best low and high beam lamps for the Lada Priora. However, it should be noted that halogen lighting elements are still the most popular.

Types of front and rear headlights for Lada Priora

Low and high beams, as well as turn signals and side lights on Lada Priora cars are structurally combined into block headlights. The built-in electric corrector allows the driver to adjust the height of the light beams from his seat, depending on the degree of loading of the vehicle.

The main manufacturers of Priora headlights are Bosch and JSC Avtosvet Plant in Kirzhach. At first glance, one gets the impression that the models are absolutely identical, but there are a number of differences - the location of the side lamps, the design and shape of the reflectors, the presence of a chrome cut on the turn signal magnifier.

The shape and number of plugs differ. The headlight units are equipped with:

• low beam lamp - H7;
• high beam lamp - AKG12–55–2 (H1);
• high beam lamp and DRL – H15;
• turn signal lamp – A12–21–4 (PY21W);
• side light lamp – A12–5–2 (W5W).

All types of conventional automotive single-filament and double-filament incandescent lamps are currently available in halogen versions. Lamps H1, H3, H4, H7 have good lighting characteristics and low cost, which allows you to create optimal lighting.

Bosch xenon lamps are in high demand due to their long service life and high-quality light. The rear lights structurally combine parking lights, fog lights, turn indicators, brake lights and reversing lights

• direction indicator – А12-21-3 (P21W);
• side and fog light – P21/4W;
• brake light – A12-21-3 (P21W);
• reversing light – A12-21-3 (P21W).

The color of the wires corresponding to each socket is indicated on the flashlight body.

Since 2013, new LED lights have been installed as taillights on Priora 2. The manufacturer has established a warranty period of 24 months for all lighting and electrical equipment, provided the client complies with the rules of their operation and performs scheduled maintenance.

Table of the best models and manufacturers

Among the highest quality, reliable and durable (400-1600 hours) lamps for the Priora car, models from manufacturers such as Osram, Philips and Bosch stand out. Let's consider their features and characteristics for the pre-restyling and restyled versions of the Lada 2170.

Bi-xenon installation

Bi-xenon is the same lamp filled with an inert gas, only equipped with a special electromagnet. It controls the Focus lamp, which allows you to create “low” and “ high ” beam. A conventional xenon lamp constantly shines at full power, and the power of bi-xenon lenses is regulated using a solenoid (electromagnet).

Lada Priora. High and low beam headlights do not work.

The principle of installing bi-xenon with your own hands is approximately the same. It differs only in the presence of a voltage controller, which is connected to the lamp, battery and ignition unit. Its main function is to control and stabilize the voltage in the wiring.

We wrote above how to install xenon yourself. Now let’s just look at the connection diagram for bi-xenon lenses and look at some of the nuances.

• The high-voltage wires from the bi-xenon lamps are connected to the corresponding wires from the ignition unit.
• The controller is connected to the power connector of the ignition unit.
• The third wire on the lamp is the electromagnet connector, which controls the intensity of the light. It also connects to the controller.
• The connector from the controller is connected to the standard lamp power connector. It has 3 contacts.
• We connect the controller to the battery power, “” and “-”, respectively.

After installation, do not forget to adjust the headlights so as not to dazzle oncoming drivers. Remember that well-adjusted headlights will ensure the safety of all road users.

Ignition unit (ballast)

On the Internet there are sometimes advertisements for the sale of headlights at a low price without an ignition unit. You should not try to save money by buying such lighting fixtures. Without ballast, the lighting will not work.

This type of device has several generations. The latest is the fifth, characterized by the most compact dimensions, ease of installation, the lowest percentage of defects, low heat generation and, unfortunately, the highest price. People who are short on funds should pay attention to the fourth generation, which has a lower price and is slightly inferior in quality.

We install xenon with our own hands

Do not neglect safety precautions when installing xenon, as you can not only damage the equipment, but also seriously injure yourself. So make sure your hands are dry and oil-free.

It is also forbidden to touch the xenon lamp bulb with your hands. In case of contact with it, it is necessary to degrease the surface with alcohol.

Once you are convinced that the process is safe, you can proceed directly to the installation. First of all, we will remove the old halogen lamps and replace them with xenon lamps. To do this, you need to remove the protective cover from the headlights. Disconnect the contact wires from the lamp and take it out. In order to safely remove the light bulb in some cars, you need to release the spring that secures it. We carefully remove the new xenon lamp from the protective bulb and insert it into the hole. Remember not to touch the flask with your hands. If you had a spring that fixed the halogen lamp, then you need to crush it. The fact is that the wires from the xenon lamps will need to be pulled through it and then brought out through a plug into the engine compartment. From the battery side, this will be a little more difficult to do, since it will partially block access to the headlight. Therefore it is better to remove it. After installing the bulbs, connect the terminals from the ignition unit to them. The next step is to make holes in the headlight plugs to run the wires through. There are two types of plugs - rubber and metal. We cut out a hole in rubber ones with scissors; in metal ones we will have to drill. It is better to use a milling cutter for drilling. The optimal hole diameter is approximately 25 mm. The stage of installing the light bulbs was the most difficult and time-consuming. Next, you need to select a location to install the ignition unit. It should be located in close proximity to the headlights so that the wires do not pass under tension. It is better to choose a place that is protected from moisture, dirt and heat. In general, high-quality ignition units should be sealed, but some manufacturers take little care of this. If you still cannot find a protected place, then simply wrap the block with electrical tape or tape. This will increase his safety, albeit partially. The ignition unit itself can be secured using clamps, double-sided tape, or attached with screws. Next, we connect the wires from the ignition unit and from the xenon lamps. Here, each wire has its own color, so it will be difficult to mix it up. You also need to connect the ignition unit to the standard electronic system. To do this, we draw another wire from the ignition unit to the connector where the halogen light bulb was connected. We repeat the procedure with the second headlight, the process is similar - we install xenon lamps, an ignition unit and connect the wires. We secure all the wiring with clamps so that it does not dangle. the excess wire into a ring.

It is better to check the correct connection using the diagram, which will definitely be in the instructions. You can also use this xenon connection diagram: Some difficulties arise when installing xenon with your own hands on cars with on-board computers. If the xenon does not function correctly when igniting or during lighting, it is recommended to install a voltage relay. It will stabilize the load on the wiring at the moment when the headlights turn on.

This video explains how to install xenon lamps with your own hands. Lamps manufactured by IL-Trade, color temperature 4300K ​​with H7 base.

How to choose a good kit

Today, there are a huge variety of xenon lamps on the automotive market. This variety makes the choice a little more complicated, and we will try to figure out which xenon is best for a particular car.

Most xenon kits consist of:

• xenon lamps;
• ignition blocks;
• wiring and fastening parts.

Xenon lamps have special markings - 6000K, 5000K, etc. It denotes color temperature - the brightness and color of the light that the lamp shines. Xenon marked 4300K ​​shines white with a slight yellow tint. They are often installed in fog lights and in the main headlights of a car. They are best suited for driving on wet asphalt.

5000K lamps produce a shade that is closest to white. Their light output power is the highest, and the light is normally perceived by the human eye. The light of a 6000K lamp has a slightly bluish tint, and is inferior in power to the two previous types, since it has the lowest light output. However, in the Russian and Ukrainian markets this type is the most popular.

The ignition unit is a device that supplies the required voltage to the xenon lamps necessary to ignite them. The more complex and “smarter” this block is designed, the more processes it controls. A high-quality ignition unit will ensure long-term and high-quality operation of the lamps, since during their ignition and glow the lamp parameters are within acceptable limits.

Colorful temperature

The most common are lamps emitting light at 4300, 5000 and 6000 Kelvin. Installing xenon on Priora is most optimal with devices with a temperature of 4300 Kelvin. Their light is as close as possible to daylight and will ensure visibility in all weather conditions. Samples with 6000K give a beautiful, spectacular, but unnatural bluish glow, which is of little help in rainy or snowy weather.

Manufacturer

Each car owner must decide for himself which company to give preference to, based on the available budget. Products from Chinese manufacturers are not worth it. Very often it does not correspond to the declared characteristics and quickly fails.

Lamps used in the Lada Priora car

For reasons of safety of drivers, passengers and pedestrians, the Traffic Rules and the Technical Regulations on the Safety of Wheeled Vehicles prohibit the operation of vehicles whose external lighting devices do not meet the design requirements of the vehicle. After all, on the one hand, it is necessary that the car is clearly visible on the road, and on the other hand, it is dangerous to blind other drivers or pedestrians with too bright or incorrectly adjusted headlights. Working brake lights will allow drivers moving behind you to keep a safe distance. There are many such nuances, and everyone can save not only money and nerves, but often also health.

Causes

If the far one is on, but the near one does not turn on, first of all, you should suspect the following malfunctions:

• destruction of the light bulb filament;
• fuse blown;
• electrical circuit problems (broken wiring).

Of course, there are more reasons, but the above are typical. All of them can be eliminated very easily.

It is important to remember that every car owner should have a multimeter in their car - this device is easy to use and allows you to detect most problems in the electrical network.

Other reasons

the high fails due to the fact that the car owner thoughtlessly makes changes to the electrical circuits of his vehicle, without having a proper understanding of their operation. If such interference took place, then you should carefully analyze your actions and check what exactly was done wrong.

When none of the above recommendations helped fix the problem, it would be better to contact a car repair shop, since, most likely, attempts to search will lead to an even worse situation. In this case, you will subsequently need much more money to eliminate the fruits of your inept actions.

The low beam does not light up on the Lada Priora: reasons, what fuse?

As practice shows, problems with low and high beams on products of the Volzhsky Automobile Plant are observed quite often. According to statistics, this problem occurs in every third car. However, most owners do not know what to do in such a situation and turn to a car service, while the breakdown is usually easily fixed and does not require any special knowledge.

In this article we will tell you what to do if for some reason the low beam on your Priora does not light up at all or only one headlight does not turn on. To be fair, it is worth noting that this kind of breakdown occurs not only in domestic cars, but is often found on foreign cars as well. For the most part, there is only one problem - wear and tear of one or more elements of the lighting system.

Lost low and high beam on Priora

If you adjust the headlights correctly , Priora will be safe to use. That is why, when inspecting the technical condition of a vehicle, increased attention is paid to this aspect. The traffic police officers do not lose sight of the quality of the lighting elements. Switched on and properly working low beam headlights improve visibility of the road.

Checking and adjusting the operation of the mechanism

Regular preventative examinations will help you avoid sudden breakdowns. According to the manufacturer's recommendations, these are carried out at least once every 3 months. Unscheduled, you will need to look under the hood if the Priora's light has become dim. Regardless of the reason, a key at “6” is required for operation.

The car owner must check the air pressure in the tires. Even a slight deviation from the norm will negatively affect the efficiency of lighting devices. After this, the vehicle is installed on the most level surface of the garage. LADA Priora is placed at a distance of 5 m from a smooth wall. The further procedure is as follows:

• install a load weighing 70-75 kg on the driver’s seat;
• place a small white screen against the wall;
• draw vertical mowing lines on it;

Direct adjustment is carried out in the vertical and horizontal plane. In order to adjust the position of the light spot as accurately as possible, you should first turn on the low beam. The setting is made for each headlight separately. In order to comply with technical recommendations, when adjusting one of the headlights, the second one must be covered with material that does not transmit light .

If you don’t have one at hand, then you just need to turn off the power. Only after this does the transition to high beam adjustment take place. The lighting adjustment process ends with a mandatory check. A vehicle rolls out of a garage onto the street at night.

The high turns on , and then the low beam. A visual inspection is carried out. If asymmetry of the light spots is noted, then the adjustment is made again. In some cases it is necessary to visit a service station.

Requirements for DRL according to GOST

Two standards regulate the operation of DRLs on motor vehicles in the Russian Federation - 41.87-99 and 41.48-2004. Detailed parameters for installing daytime running gear in a car are described:

• The lower edge of the headlights should be at a distance of 25 cm to 1.5 m from the ground surface (the vehicle's ground clearance is not taken into account);
• The distance between the “inner” edges of the two headlights can be strictly from 60 cm;
• The distance from the “outer” edge of the headlight to the edge of the bumper should be a maximum of 40 cm;
• The area that the light from daytime running lights must cover must be between 25 and 200 square centimeters;
• The maximum permissible brightness of the lights is 800 Cd, the minimum is 400 Cd.
