Adjustment of headlights

For traffic safety the correct adjustment of headlights has great value. Exact adjustment of headlights is possible only with use of the special device. Therefore here only is shown, where it is possible to regulate headlights, and what conditions should be executed for the correct adjustment.

1 Pressure of air in tires should correspond to the established value.
2 not loaded car should have cargo in mass of 75 kg on a place of the driver.
3 Fill a fuel tank at least for 90 %.
4 Establish the car on an equal platform.
5 Several times strongly press through a forward part of the car that the suspension bracket adopted the working provision.
6 Establish a regulator of range of light on “0”.

At cars with xenon lamps of a passing beam (the additional equipment) after inclusion of light wait for not less than 30 with that automatic adjustment of range of light was adjusted.

7 Headlights are authorized to be regulated only on a passing beam. The inclination of a beam of light for normal headlights makes 10 cm on 10 m of length.

8 Adjust headlights by rotation of adjusting screws-1-and/or
- 2-.

1 adjusting screw for adjustment generally down
2 adjusting screw for adjustment generally across

On an illustration the left headlight is shown, at the right headlight adjusting screws are located specularly. At rotation of the adjusting screw the beam of light moves always on a vertical and a horizontal. The unidirectional arrangement of adjusting screws is impossible.

The inclination of a beam of light for a fog light makes 20 cm on 10 m of length.
