Do-it-yourself headlight adjustment repair for VAZ 2110

Even with a perfectly adjusted high and low beam light beam, you often have to adjust the angle of the headlight reflector. This is primarily due to the loading of the car. If, according to the rules for adjusting the headlights of the VAZ-2110, we start from the load of the driver + front passenger, then in real life, when the cabin is fully loaded, our adjustment will leave no stone unturned. The rear of the car will squat, the front will rise and the light beam will blind oncoming drivers. To quickly adjust the angle of the headlight reflector, a hydraulic corrector is installed in all VAZ-2110s.

The principle of operation of the VAZ-2110 headlight hydraulic corrector

Its purpose is clear - without leaving the cabin, the driver can change the angle of the light beam relative to the road. The device must work correctly with two headlights at once and have a sufficient range of adjustment - to maximize the angle of the reflector when the rear part of the body is fully loaded, and also reduce the adjustment to zero when the load is minimal.

The principle of operation of the headlight hydrocorrector.

The VAZ-2110 hydraulic corrector, installed as standard, consists of:

main hydraulic cylinder and switch, both of them are assembled in a single block and installed to the left of the steering wheel on the front panel;
hydraulic drive system, line - tubes that connect the elements of the system;
working hydraulic cylinders, actuators that raise or lower the headlight reflector;
working non-freezing liquid.

The low-pressure hydraulic system allows you to change the working pressure and move the rod of the working cylinders within 6–7.5 mm . In theory, this is enough to change the angle of installation of the reflector from minimum to maximum and, accordingly, change the direction of the angle of the light beam.

Electromechanical types of correctors

This type of device is high-tech, it is the most popular and widespread. Its design is simple, consisting of several elements:

Geared motors for each headlight.
4 position switch.
Wiring.
Fuse.

If you use such a device, you will need to do the following:

Remove (if installed) the hydraulic corrector drive.
If you plan to install the switch in another location, then the first step is not necessary. The most suitable place to mount the switch is to the left of the steering wheel.
Lay the electrical wiring to each headlight. It is advisable to connect the wires to the harnesses with special plastic ties.
Install new stepper motors in place of the adjusting rods of the old hydraulic corrector.
Connect the wires to the stepper motors.
Since this device consumes, albeit a small current, it is necessary to install a 7.5 Ampere fuse in the positive gap of the power supply. This device will save you from a short circuit. But it is best to calculate the maximum current consumed by the entire system. Based on this value, select a suitable fuse with a margin of 25%.

It is best to connect the VAZ-2109 headlight electric corrector to the wiring that comes from the ignition switch. This will completely de-energize the circuit when the ignition is turned off, and this will increase the reliability of the device and safety.

Malfunctions and diagnostics of hydraulic corrector

Despite the simplest design, the hydraulic corrector is considered one of the most unreliable systems in cars of the tenth family. Design flaws, quality of materials and workmanship force us to return to the problem of adjusting headlights almost every year.

In this case, neither the working nor the main cylinders can be repaired and require replacement if they fail.

The signs of a malfunction are clear - the headlights do not respond to the corrector knob and are frozen in one position . The most common problem is depressurization of the hydraulic system. This trouble can be easily calculated by the leakage of liquid from the system, and it is also easy to eliminate. It is enough to seal the joints (on the cylinders) of the hydraulic system and check its operation again.

Another problem is fluid leakage through the cuffs of the working cylinders . No one is going to repair cheap plastic cylinders; they are replaced with new ones. By the way, the price of a new hydraulic corrector for the VAZ-2110 and all cars of the family (article 2110–3718010 and 2110-3718010-10 ) is 450–550 rubles, depending on the manufacturer. The difference between them is the stroke of the working cylinder rod. For tens in a station wagon, a larger load and a larger adjustment angle are provided. Accordingly, a larger stroke of the cylinder rod.

You can check the operation of the headlight hydraulic adjustment system by measuring the working stroke of each of the working cylinder rods:

2110–3718010 — working stroke 6–7.5 mm for sedan and hatch;
2110-3718010-10 — working stroke 6–8.5 mm for a station wagon.

If the hydraulic cylinders do not work or the working stroke does not correspond to the nominal values, we replace them and install a previously purchased new hydraulic corrector of the appropriate modification.

Purpose and tasks

Actually, even from the name of this device you can almost immediately guess what the purpose is and what the headlight hydrocorrector is used for. Of course, it is necessary when you periodically change the load on your car, which leads to a difference in the angle of the headlights. In principle, all hydraulic correctors are made so that the driver does not interfere with them and does not carry out repairs on his own, but...

What to do if it fails and no longer performs its functions? Nothing special, except that the hydraulic corrector is sold fully assembled and if it malfunctions, it needs a complete replacement, and not attempts to repair or fix anything. In general, in such cases, you can, of course, commit yourself to a stupid repair idea, but it is much more advisable to simply replace the hydraulic corrector with a new one.

Replacing hydraulic corrector VAZ-2110

There shouldn’t be any difficulties during replacement; we only need standard tools for the job, and we can change the hydraulic corrector even in the field.

The only thing that will make it easier to unscrew the hydraulic corrector switch mounting nut is ordinary tweezers.

Let's get started:

Open the hood, loosen the clamps, and release the hydraulic drive line pipes.
Remove the working cylinders by releasing the clamps using a flat-head screwdriver.

Open the hood and remove the actuator cylinders from the inside of the headlights.

As you can see, replacing the system is not at all difficult and it will not take much time. But the new hydraulic corrector will only work for a year or two , after which the operation will have to be repeated. By the way, there are electric headlight levelers on the market (from 3.6 thousand rubles) and electromechanical automatic ones (from 6–8 thousand). Their service life is much longer, and the adjustment accuracy is better than that of a hydraulic system.

Good luck with your choice and bright, accurate headlights on night roads!

Removal and replacement

Remove the negative terminal of the battery. By pressing the latch, turn the hydraulic corrector towards you and remove it. Having removed the sealing ring in the headlight housing and installed a new one in its place, we insert the electrical corrector into it. In the same way, we remove the hydraulic corrector of the other headlight and replace it with an electric corrector.

Already in the cabin, we disconnect the switch to which the hydraulic corrector is connected, and connect the electric corrector using wires.

Thus, the new corrector has been installed and will be able to perform its duties on the VAZ 2110 more clearly. Almost everyone who changed the hydrocorrector to an electric corrector is more satisfied with its performance than the previous corrector, which behaves more “gently”, often unpredictably.

It's no secret that most accidents on the road occur precisely when the sun goes down and darkness sets in. Some motorists simply forget to turn on their headlights, for others they do not work, and still others completely blind oncoming cars with their incorrectly adjusted lights.

Headlight adjustment

In order not to create problems for yourself and other road users, it is necessary to make adjustments. This need arises when replacing headlights, or after long-term use of a vehicle in which, due to vibrations and unevenness on the road, the glow geometry of the head optics is disrupted.

Repair of hydraulic corrector for VAZ 2110 headlights

Adjusting the light beam happens quite often, especially when the trunk of the car is heavily loaded; the light shines directly into the eyes of drivers of cars moving towards you. If the reflector has dropped and the adjustment does not work, our instructions will help you repair the headlight hydraulic corrector of the VAZ 2110; the repair will take very little time.

VAZ 2110 headlights Kirzhach - hydrocorrector repair

Unscrew the headlight fasteners and remove them;
We disassemble the headlights: carefully remove the glass, then the metal clips (6 pieces);
Using a knife, clean the glass from the sealant;
We cut off the convex profile (in the shape of the letter P) on the glass;
Unscrew the screws (there are 3 of them) from the reverse side;
Take out the paper reflector;
Next to the hydraulic corrector hole inside the light housing there is a spring that must be removed;
We perform the same actions with two plastic rosettes from two “turntables” securing the reflector.

Note: The hydraulic corrector ball snaps into a plastic groove, and the metal bobbin snaps into the second groove. It stops the adjustment, preventing it from being unscrewed further than itself. If you press the hydraulic corrector when adjusting the headlights, the metal latch will break. The ball will pop out of the plastic and then the headlight will “fall”;

The repair will consist of replacing the broken latch with a gasket , which will not make it clear that the adjustment has reached the extreme position;

Broken iron latch of hydraulic corrector

Rubber gasket to replace a broken latch

As a result, there is a high probability that the corrector will be compressed again;
The correct solution is to improve the fastening by inserting a cotter pin made of solid wire between the petals of the plastic thing.

For the VAZ 2110, the repair of the headlight hydrocorrector has been completed. We assemble the headlights in the reverse order of disassembly. We first clean the old sealant, then apply a new one.

Second repair method

We cut threads on the adjustment screws (metric 3);
We screw them into the illuminator itself, then put on the washers;
We take out the plastic fasteners;
We put on the bar with the high beam and low beam modules located on it;
We put a washer on top, a spring washer, and another washer on top of the spring. The use of a lock nut is recommended;
We twist everything;
We fix the structure using anaerobic sealant.

How does he work

It consists of:

Regulator with control knob. It is installed in a sealed container with liquid
There are two tubes for each headlight. They transmit pressure from the regulator to the actuators on the reflectors
Working pistons. They are also the mechanisms responsible for changing the position of the reflector. The change in pressure from the regulator is transmitted to them through tubes and, depending on it, the rod extends or recesses into the depths of the corrector piston.

Let's look at the principle of operation in more detail.

This entire system is sealed. Antifreeze or liquids based on it are poured into the headlight hydrocorrector. This is necessary so that during frosts it does not freeze and the system does not lose its tightness, breaking the plastic tubes.

The driver, turning the regulator in the cabin clockwise, sets in motion the piston, which is located in the main cylinder of the hydraulic corrector. It has a threaded part. By rotating, the corrector rod is screwed into the cylinder cavity, creating excess pressure in it. In simple words, it begins to put pressure on the liquid poured into it.

This pressure is transmitted through the tubes to the working cylinders located in both headlights. The excess pressure that is created in them pushes the pistons out. This raises the reflectors upward. To understand how this works, let’s look at the design of the headlight unit in more detail.

Advertising:

Inside the headlight consists of:

Reflector
Top holder
Adjustment lever
Return spring
Vertical adjustment screw
Hydrocorrector rod
Bottom support

The upper headlight reflector holder is attached to the reflector. It is connected to a lever, the upper end of which rests against the vertical adjustment screw, and the other end against the corrector rod. The return spring presses the lever against the rear headlight cover, lowering the reflector as far as possible.

Advertising:

The piston of the hydraulic corrector working cylinder moves forward, pushing the lever. It, having an upper fulcrum on the adjusting screw, pulls the reflector back with its upper part. The reflector changes its angle of inclination relative to the horizontal line and the headlight begins to shine upward.

The driver turns the interior corrector regulator to position “2” or “3”, the pressure in the system decreases, the working pistons are recessed into the depths of the cylinders. The lever, under the action of the return spring, is pressed against the rear wall, pushing the reflector forward. The reflector lowers, the light beam shines down.

There are frequent cases when the driver notices that the headlights are shining downwards, adjustment with the corrector does not give the desired result, the direction of the light beam does not change. This occurs due to breakdowns in the headlight hydraulic corrector system. Let's take a closer look.

We repair the light fixture without disassembling it

You can snap the ball into place without removing the glass, through the holes of the light bulbs on the back side of the illuminator:

We drill a hole exactly opposite the latch at the top of the headlight;
Insert a screwdriver into the hole;
Attach the collet to the corrector ball;
We seal the hole we drilled;
We attach a hinged loop from a furniture cabinet (hinges 5-6 centimeters long, with mounting holes and a cutout on top on which it is attached) to each broken corrector unit;
We insert the canopy into the slot of the adjustment screw;
We move the screw so that the slot is in a narrow place of the canopy;
Holding the canopy, unscrew the screw until it stops with force. This is how the canopy is fixed, which needs to be placed in a horizontal position;
Using an electric drill, using a 3 mm drill, we make a hole in the base of the light where there is a hole on the canopy;
We screw a shortened screw into the hole so that it does not reach the high beam reflector. This slot secures the adjustment screw securely; it can be broken again.

Lighting problems

If the illumination of the road with headlights has deteriorated, then you should first determine the cause of this malfunction. You may not need to adjust your headlights. First you need to carefully wash the lens of the device. It may well be that the reason is simple - pollution. To avoid having to constantly wash the lighting fixtures, it is recommended to install a washer. Installation of the device does not cause problems, and the working fluid is supplied to it from the windshield washer.

Next, you should check the integrity of the lens. If small cracks, damage from small stones or other defects are found, this may lead to scattering of the light flux. The lens needs to be replaced. Abnormal operation of headlights can also be caused by defects on the surface of the reflector.

Perhaps, for various reasons (for example, defects), the reflective material began to deteriorate, which does not allow creating the desired concentration of the light beam. This reflector needs to be replaced urgently. Finally, the light element itself no longer satisfied the driver’s wishes.

Installing a halogen light bulb instead of a regular one will significantly enhance the lighting.

Eliminating headlight shake

Many owners of the VAZ 2110 find that the light flickers when the car is moving. Such a breakdown most often occurs in Kirzhach headlights, but in Bosch parts such a breakdown rarely occurs. There is only one reason: reflector rattling. To eliminate light flicker, check:

Is the reflector in place in the latch;
The presence of an adjusting bolt rod;
The emphasis is on the seating recess of the hydraulic corrector rod;
We check the sagging of the thread (swap the high beam and low beam bulbs);
Integrity of the tube in the hydraulic corrector (it may fray).

Preparing to adjust the light output

In order to improve visibility on the night road, without dazzling drivers of oncoming cars, it is necessary to adjust the headlights. You can do this in a service center, or with your own hands. Knowledge of the basic rules for adjusting headlights will help improve the luminous flux on a VAZ.

So let's get started:

Serviceability. Make sure that your hydraulic corrector or electric headlight corrector is working correctly (depending on the configuration). Please note that the corrector plays an important role, therefore, before the adjustment takes place, you need to be sure that this mechanism is working properly;
Position. Having chosen a completely flat area, install the car. The area must be checked with a level to prevent distortion, otherwise it will not be possible to adjust the headlights correctly;
Build a kind of vertical shield screen at a distance of 5 meters from the car on which you can draw;
It’s not bad if you have a flat area in front of the garage door. They are also unlikely to be particularly harmed by chalk;
Loading. A car that is being adjusted must be “fully equipped” - fueled, with normal tire pressure, and a load of the driver’s weight (or a person of approximately the same weight) placed on the driver’s seat;
Vertical markings. On the screen, wall or garage door, draw three vertical lines and mark them: “O” - there will be a line in the middle of the car (this place is usually indicated by the sign of the car, in our case it is the usual VAZ sign); “L” means right;
Horizontal marking. Draw a horizontal line through the centers of the headlights, marking it N, and 65 mm below it, draw another line, which is marked “P”. Now it becomes possible to adjust the light with your own hands.

Adjustment process

To increase accuracy, you should additionally prepare the following tools:

building level;
thick fabric or cardboard;
window cleaner;
gloves;
wheel chocks;
clean napkins.

Using a level you can determine the position of the body and significantly improve the quality of adjustment. Before making adjustments, you need to wash the headlight with window cleaner and wipe dry with napkins.

Place the machine on the site. The distance from the wall should be 5 meters.
Place the load in the driver's seat or place an assistant in it.
Rock the body to relax the silent blocks and springs.
Check the slope of the body with a level.
Set the electric corrector to the zero position.
Mark the center of the machine with a vertical line on the wall.
Draw lines A and B at a distance of 1108 mm.
Draw a height mark of 60 cm with a horizontal dotted line.
Move 75 mm down from the main horizontal designation and draw a thick line.

Clear marks on the wall will increase the accuracy of the headlights during the work process.

To adjust the beam, you cannot use the hydraulic corrector: it must be at level 0. All adjustments are made manually, using special screws built into the headlight housing.

You can raise the headlights on a VAZ using a screw located near the radiator grille. To turn the reflector left or right, twist the plastic handle, which is located near the wing.

If the screw is tight, you need to unscrew it all the way, apply a drop of oil and screw it back. When turning the handles, do not apply force: this will break the reflector or disrupt the angle of the rod.

turn off the VAZ engine;
to turn on the light;
cover one headlight with cardboard;
use the handles to align the headlight beam according to the diagram;
adjust the second VAZ lamp.

With correct adjustment, the cut-off line should coincide with the main horizontal mark, and the places where the line transitions into a daw should rest against points A and B. The adjustment is considered complete if the headlights shine in accordance with the schedule and do not cast light beyond the marks.

Changing the type of optics (tuning)

Car enthusiasts often tune their car headlights to improve their appearance. High-quality tuning gives the car a fashionable look and beauty. If you choose the right accessory, the appearance of dozens will change completely . The most popular among car enthusiasts is tuning headlights in the form of tinting. It is carried out in a variety of ways that have virtually no effect on the brightness and quality of road lighting. Types of headlight tinting:

Painting of the headlight mask;
Glass painting;
Glass tinting film.

The process of such tinting is best shown in a video. For those who don't want to paint or tint their headlights themselves, there are ProSport headlights. They are already sold in black or chrome. You just need to install them instead of the standard headlights. Only they cannot boast of high quality or bright light.

Depending on how loaded the vehicle is, the headlights can be directed higher or lower. To adjust the light flux, special devices are used - hydrocorrectors. If the car is loaded, the headlights should be turned down so that the flow of light is directed not upward, but onto the road. This ensures the necessary illumination of the road surface and prevents the driver of an oncoming car from being dazzled. In the case of a minimal vehicle load, when the rear part of the frame is raised, the headlights should be turned upward.

Operating principle

The corrector is designed to adjust the level of the cut-off line in low beam headlight mode. For the long-range glow mode, this option is not so important, since only the low beam headlights have a clear cut-off line (the conventional border of the light flux, abruptly turning into a practically unlit area). The low beam of the headlights should illuminate the road well, but not dazzle oncoming drivers.

The level of the cut-off line depends on the shape and vertical angle of the reflector. It is the last parameter that needs constant adjustment, since the angle of the headlights depends on the degree of load and distribution of cargo in the car. The more the rear part is loaded, the more the front of the car will be raised. Accordingly, even correctly adjusted headlights will now blind drivers of oncoming cars.

According to the requirements for cars manufactured in Europe, all cars approved for operation after 1999 must be equipped with a headlight leveler as standard. Such systems are not installed on cars with active suspension.

Enforcement systems

The headlight range control is controlled by changing the position of the switch on the dashboard. The main types of drives used in the design of manual correctors:

mechanical. The design can only be called a headlight corrector, since the device is an adjusting screw mounted in the headlight housing. Screwing or unscrewing the latter leads to a change in the vertical angle of inclination of the reflector;
hydromechanical;
electromechanical;
pneumatic. Due to its complexity, the pneumatic headlight leveler has gained little popularity. The system can have manual or automatic adjustment. In the first case, the pneumatic actuators are controlled by the driver via an n-position switch on the dashboard (most often used in conjunction with halogen lighting). The operation of the automated system involves body position sensors, a control unit, and actuators (used in conjunction with xenon lamps). The position of the reflector is regulated by changing the air pressure in the corresponding lines.

Hydrocorrector

This system is well known to domestic car enthusiasts, since manual headlight levelers of this type were installed on VAZ 2107, 2109, 2110, 2114, Niva, and Granta.

6 – knob for adjusting the light beam;
1 – main adjustment mechanism;
2 – working cylinders with a rod acting on the headlight reflector.

The operating principle is based on adjusting the position of the corrector rod by moving a special fluid along the lines. The switch is mechanically connected to the piston of the main hydraulic cylinder. When the regulator handle is operated to raise the reflectors, the fluid pressure in the system increases, which drives the working cylinders, thereby extending the rod. Since the system is completely sealed, moving the handle back has the opposite effect.

Electromechanical corrector

The electrically driven headlight reflector adjustment system has become the most widespread. The electric drive allows for both forced change in the height of the light beam boundary and automatic adjustment depending on actual driving conditions.

Design of headlight hydraulic correctors

As a rule, the following components are included in the design of a hydraulic corrector:

master cylinder mounted on the dashboard;
actuator cylinders mounted on the headlights;
connecting pipelines that are fixed with clamps;
working fluid with increased frost resistance.

Typically, hydraulic correctors are made in the form of a non-removable structure that cannot be repaired. Therefore, if, for example, the hydraulic corrector of the VAZ-2114 headlights fails, it is repaired by replacing it with a new set.

The manufacturer provides a maximum operating pressure in the normal state of the corrector. To direct the luminous flux of the headlight downwards, the pressure in the system is reduced, as a result of which the actuator cylinder rod is retracted and the optics are rotated downwards. Thus, most of the time the device is under increased pressure.

Quite often, when temperature changes occur, especially in winter, the structure of the seals is damaged due to the poor quality of the rubber, which leads to leakage of the working fluid. In turn, this leads to jamming of the cylinder pistons in one of the positions.

Structurally, all hydraulic correctors that are installed on VAZ vehicles are made according to a similar design, with the exception of some differences in size, layout of cylinder fastenings and pipelines. Today the following modifications of hydraulic correctors are supplied to the market:

“2105-3718010” - for VAZ 2105-2107;
“2108-3718010” - for VAZ 2108-21099;
“2110-3718010” and “2110-3718010-10” - for VAZ 2110-2112;
“2114-3718010” - for VAZ 2113-2115;
“21213-3718010” - for 21213 “Niva”.

Electric corrector

By assembling the circuit shown in the figure, you can check the smooth operation of the servo drive. If the gear motor does not respond to power supply, you can safely proceed to replacing or disassembling it. In most cases, the housing is secured with plastic latches. If the latches cannot be snapped off, they can be carefully cut off, and when installing part of the body, they can be joined with dichloroethane (special glue for plastic). The electric motors themselves fail extremely rarely, but they are also sold separately.

How to repair a hydraulic corrector on a VAZ 2110 – 2115

Repair of the VAZ-2110 headlight hydraulic corrector is not provided by the manufacturer. Therefore, if it fails, the entire device, complete with pipelines and cylinders, is replaced.

If the angle of inclination of the optics is not adjustable when the vehicle load changes and it is not possible to achieve the optimal luminous flux using the adjusting screws on the headlights, you should check the functionality of the corrector as follows:

First of all, it is necessary to inspect the device for the integrity of the pipelines and the absence of liquid leakage.
If after these measures no malfunction is detected, we proceed to checking the performance of the actuator cylinders. To do this, remove them from the headlight unit and measure the stroke of the rods. Normal operation of the cylinders is ensured when the rod stroke is within the range of 6.5-7.5 mm.
Since repair of the VAZ-2110 headlight range control is not structurally provided for, we replace the non-working device with a new device included in the kit.

Rear light tuning

We offer one of the options. For this you will need:

LEDs;
knife;
organic glass;
tape measure, ruler, flexible meter;
pencil, compass (marking);
resistors, silicone.

Here's how to remove the headlights: the devices are disassembled, the glass is fixed by soldering, not glue, so the corner is cut off. When the knife is inside, the glass is removed. Then the headlight parameters are determined and plexiglass blanks are made from them. Holes are marked, drilled, diodes are glued in with superglue, resistors are soldered in, and then the whole thing is sealed with silicone glue. Then everything is assembled and glued, the seams are sealed with a silicone compound, thanks to which water will not get in there.

Adjusting the headlight range control rod

Sometimes a malfunction of the headlight adjustment system can be caused by a misalignment of the adjustment lever with the lampshade rod. Therefore, if, for example, the hydrocorrector of the VAZ-2112 headlights does not work, do not rush to repair it by replacing it. First, make sure that the connection between the lever and the rod matches the operating position.

The rod of the corrector actuator cylinder rests on the lever, which, in turn, acts on a similar rod rigidly fixed to the headlight dome. The lever passes through the adjusting bolt, which is its fulcrum. The adjustment mechanism works on the principle of a swing. The corrector swings the lampshade, and the adjusting bolt allows you to raise or lower the support point of this swing. If the bolt is turned to the maximum position, the reverse end of the lever in the form of a ball may slip out of engagement with the lampshade rod.

In order for the VAZ-2115 headlight hydraulic corrector to work again, the device must be repaired by returning the lever to a special recess on the rod. To do this, first tighten the adjusting bolt until it stops, then press the lampshade down and insert the lever ball into the desired position.

Self-adjustment

Adjustment diagram Before you start adjusting, you will have to remember your geometry lessons, and also use your draftsman skills. After all, to adjust the glow of the optics, you will need to draw something on the wall.

Find a wall that has a flat area adjacent to it. Surfaces must be absolutely flat. Without this condition, adjusting the headlights makes no sense.
The light should be directed towards the wall without any obstructions. That is, there should be no foreign objects in the path of the light.
Move 5 meters away from the wall.
Put a friend behind the wheel who will help you. It is advisable that his weight matches yours. If it weighs less, add some weight to the interior.
Now we proceed to drawing the drawing according to the image we offer.
The E marks are the middle of your car's headlights. Three vertical lines are drawn through them - A, O and B. They must be symmetrical to the axis.
Measure the distance from the base of the platform to the middle of the front optics. According to the standards, it is 600 millimeters.
On the wall, draw a horizontal line 1, which is located 600 millimeters from the base of the floor.
Draw line 2 parallel to line 1. It should be 75 millimeters below line 1. This line will be the middle of the light spots.
If you have a hydraulic corrector, an assistant will need to turn the corrector handle to the position without a passenger load.
Now turn the optics to low beam mode.
Take turns blocking the light with cardboard or cloth that blocks it out.
Turn the adjustment screws to achieve the desired result.
The right headlight is adjusted first, and then the left.
According to the instructions, the upper edges of the light spots should run along the second line, and the inclined and horizontal sections should coincide at points E.

The procedure looks quite complicated, but in reality you just have to draw a few lines and take precise measurements in millimeters.

The most difficult thing about self-adjustment is finding a perfectly flat platform and wall. Not every garage has these. And hardly anyone would want to level the floor and wall for a procedure of this kind.

It is more than possible to correctly adjust the optics with your own hands. But in practice, it is better to entrust this task to specialized service stations. They have the necessary equipment and, most interestingly, a flat floor and a perfectly flat wall.

Do you adjust the headlights yourself?

Replacing the hydraulic corrector for VAZ 2110, 2111, 2112 headlights

Replacing a faulty corrector yourself is not difficult. The replacement sequence is as follows:

unscrew the screws securing the pipeline clamps to the mounting brackets;
remove the handle from the master cylinder;
Unscrew the nut securing the master cylinder to the dashboard;
We disconnect the actuator cylinders from the headlamp;

Many car enthusiasts, instead of the standard hydraulic corrector provided by the manufacturer, install a more practical and efficient electric headlight corrector. Its difference from a hydraulic device is that electric motors are used as a drive. For VAZ cars, a standard electrical corrector of the Silich-Zenit series is provided. It is easily mounted in the same places as a conventional hydraulic corrector. The installation procedure for the electrical corrector is as follows:

disconnect the negative terminal from the AC;
turn the master cylinder counterclockwise and remove it;
replace the o-ring;
install the electric corrector in place of the main cylinder;
dismantle the master cylinder lever in the cabin;
We connect the positive terminal of the corrector to the socket of block No. 20;
We attach the negative terminal to one of the body studs under the dashboard;
we lay the corrector wiring instead of pipelines or along the power supply harness;
connect the corrector's electrical wiring to the actuators;
connect the negative terminal to the battery;
We check the functionality of the corrector.

After installing the corrector yourself, you will have an idea of how this device works. If necessary, repairing the electrical corrector will not be difficult.

How to adjust the headlights?

1) First, at night, place your car parallel to any vertical surface, which can be a garage, a wall, or other obstacles.

Note! The car must be positioned strictly five meters before the obstacle!

2) Then, if possible, use chalk or a marker to draw the following figure on the obstacle near which you are going to adjust the headlights:

Note! If it is not possible to draw a picture, then when adjusting the headlights, recreate it in your head!

3) Next, turning on the low beam headlights, and at this time covering the left headlight with a thick piece of fabric, first adjust the right headlight, to do this: 1. Turn screw “1” in the direction you need, adjust the position of the headlight light vertically. 2. After holding screw “2” with your hand, adjust the position of the headlight light horizontally.

Adjust the position of the headlight until it matches the drawn pattern on the obstacle, namely: 1. Vertically, without fail, the light must touch the “N” line and not go beyond the “M” line. 2. And horizontally, without fail, the light must come into contact with the lines “C” and “D”.

4) When you finish adjusting the right headlight, do the same operation with the left headlight.

Important! 1) In order to achieve the most accurate headlight adjustment, before starting the adjustment, the car must be fully filled with gasoline! 2) And also when adjusting the headlights, it is recommended to place a person approximately your build, or, to be more precise, the same weight as you! 3) Before starting the adjustment, it is also worth checking the pressure in the wheels, and if necessary, bring it to normal!

Features of restoration of hydraulic correctors for VAZ 2107—2109

As a rule, on cars of the VAZ 2107-2108 series, a manual hydraulic headlight leveler is installed. With it, the driver can manually change the direction of the light flux depending on the load of the car, moving the headlights up or down within small limits.

The design does not provide for repair of the VAZ-2107 headlight hydraulic corrector, therefore, if it fails, it is replaced with a new device. The only thing you can try to do if it is impossible to adjust the angle of the headlights is to adjust the operation of the corrector in the order indicated above.

There are no fundamental differences in the optics adjustment device in the “nine” compared to other models. Therefore, the VAZ-2109 headlight hydraulic corrector is repaired using the replacement method.

How to use concealer

The corrector has knob A on the dashboard of the VAZ 2107 to the right of the steering wheel, next to knob B for adjusting the brightness of the dashboard lighting. If you rotate knob B counterclockwise, the brightness of the light decreases.

As they say, the control knob of the device has an “intuitive interface.” To change the direction of the light flow, with the trunk loaded and the headlights on low beam, you need to align the mark shown on the regulator with one of the marks marked on the unit body so that the beam of light does not blind oncoming drivers.

The VAZ 2107 hydraulic corrector has four switching options (in order from large point to small point):

I - minimum load, the front of the car is slightly lowered: one driver, or there is a passenger in front;

II - driver and four passengers, the body sags evenly downwards;

III - the same as II, with an additional load of up to 75 kg in the trunk:

IV - driver and maximum trunk load: the “nose up” the most.

In order to see how the angle of inclination of the light beam changes during operation of the corrector, it is better to place the car perpendicular to the wall. Let us recall the standard requirements for the location of the low beam.

Why does a car need fog lights?

The headlights, parking lights and warning brake lights that make up the optical system perform their specific functions in detecting cars on the roads and driving a car in the dark. In addition to them, many cars are also equipped with fog lights. Correct selection and installation will allow them to be used not only in fog, but also in other situations. Not everyone knows what these headlights should be like, how to use them for their intended purpose, and how they differ from conventional lighting devices.

Most drivers are convinced that these headlights should only have yellow glass or light filters, although the Rules stipulate that fog light filters can be painted white or yellow. They are of the opinion that yellow light travels further in fog than normal light. In fact, color has little effect on the range of light in fog.

In fog lights, the main role is played by the correct direction of the light flux. The headlight generates a luminous flux wide in the horizontal plane and narrow in the vertical plane, which is located low above the road surface and directed along it. It is known that fog rarely reaches the ground. Therefore, it turns out that the fog is, as it were, illuminated by headlights from below.

At the same time, the road is illuminated, and the rest of the space is hidden in the shadow of fog. Thus, the fight against fog is carried out through a special distribution of the light flux. Yellow and white light have the maximum intensity of light energy in their spectrum, compared to which the energy density in red, green, blue, and violet light is much less.

Even the most correctly installed fog lights provide visibility of the road in fog no further than ten meters. But this is quite enough, since in fog cars move at extremely low speeds. The advantage of these headlights over conventional ones is that they also illuminate the side of the road, allowing you to see the side markings on the roads.

You can turn them on while driving along with the side lights. Some drivers install a red light at the rear, which burns brighter than the brake light and side lights, and allows the driver of the vehicle behind to notice the car in the fog earlier. This lamp, just like the main beam of conventional headlights, must be turned on regardless of the time of day if fog has fallen on the road.

Rear red fog lights

Fog lights can be used with benefit for traffic safety not only in foggy conditions, but also under normal conditions at night. For example, they are extremely useful in the dark on narrow mountain serpentines and winding forest roads, when you need to constantly monitor the side of the road. On such roads, it is recommended to turn on the fog lights in conjunction with the low beam of the main headlights. This improves visibility of the road and side of the road. Proper use of the lighting devices available on your car will allow you to confidently navigate in difficult weather conditions.

Repair without replacing the corrector

The hydraulic corrector should be replaced only in case of fluid leaks. Also if it cannot push the slave cylinder, for some reason. Most often due to faulty tubes. But sometimes the cause of failure is not the cylinder itself. Then repairs can be made without replacing this part. The correction mechanism itself is located in the headlight unit. It consists of:

Metal ball;
Plastic clip;
Bobbins;
Limiting groove on the headlight housing;
Return spring.

The working cylinder, resting against the bobbin, moves the ball along the groove, thus lowering the headlight. When the cylinder piston moves back to its original position, the spring pushes the cage with the ball back. It often happens that during adjustment a plastic part cracks or a spring bursts. This can be easily fixed without replacing the entire system.

To do this you will have to remove the headlight. Remove the light bulbs from it. Remove the glass. It is attached with sealant and 6 metal clips. Next, the spring is removed from the reflector and, after unscrewing a couple of screws, it is removed. After this, the damaged parts are replaced. Reassemble in reverse order.
