Infringement of adjustment of a direction of optical axes of head headlights can lead to blinding of drivers moving a parallel course of vehicles and be at the bottom of emergency creation on road. Check of correctness of adjustment of headlights should be made regularly time in 12 months, and also each time after replacement of block headlights and performance of repair of bearing elements передка the car. It is necessary to pay attention of readers to that fact that it is possible to consider the procedure described more low as only preventive adjustment. Definitive adjustment of optical axes should be made in a specialised workshop of car-care centre!

Each of block headlights is equipped by two adjusting screws. One of screws serves for adjustment of position of a headlight in the horizontal plane, the second – in vertical (address to an illustration above).

There are some methods of check of correctness of adjustment of a direction of optical axes of head headlights of the car. Elementary of them, not demanding from the executor of any special skills and not requiring application of the special equipment is more low described.

The scheme of adjustment of a direction of an optical axis of head headlights

1 — the Stain of the maximum light exposure
2 — the Line of crossing with a wall of the horizontal plane passing through the centres of lenses of block headlights
3 — the Line of crossing with a wall of the vertical plane spent through the centre of a lens of a block headlight of in parallel diametrical plane of the car
4 — the Diametrical plane of the car
5 — 7.6 m
6 — the Surface of lenses of block headlights

PERFORMANCE ORDER

1. Drive the car передком to a wall. Paste on a wall an adhesive tape strip on the vertical line which are passing in a diametrical plane of the car. Also paste vertical strips of an adhesive tape on the lines passing through the centres of projections to a wall of lenses of head headlights (address to an illustration above).
2. Paste on a wall horizontally located strip of an adhesive tape on a line spent through the centres of projections of lenses of head headlights on a surface of a wall.

The given procedure to make easier, having adjusted the car closely to a wall.

3. For performance of adjustment of a direction of optical axes of head headlights roll away the car from a wall on distance about 7.6 m.

The platform on which the car takes places, should have an equal horizontal surface, it is desirable with a firm covering. The fuel tank of the car should be filled half, from salon and a luggage space all heavy subjects breaking centering of the car are taken.

4. Begin with adjustment of a direction of an optical axis of a passing light. Try to achieve rotation of adjusting screws of block headlights of such arrangement of light stains that zones with the maximum intensity of illumination it has appeared approximately in 50 mm below a horizontal line and on туже size more to the right of vertical.
5. Having finished the first adjustment, include a headlight: zones of the maximum intensity of light exposure should be displaced in a direction of crossing of vertical lines with horizontal, it having appeared hardly below last.

To receive equally full centering of beams both near, and a headlight in practice it is not obviously possible. It is necessary to try to achieve some conciliatory proposal taking into account features of operation of the car, holding at the head of a corner aspiration to provide the maximum traffic safety.

6. At the first possibility drive away the car on a car repair shop for performance of adjustment of a direction of optical axes of head headlights with application of the special equipment.
