Headlight beam direction — adjustment (VAZ-2104)

Attention! The direction of the headlight beams should be such that the road in front of the car is well lit, and oncoming drivers are not blinded when the low beam is turned on.

Screen layout diagram for headlight adjustment: A - vertical line indicating the location of the low beam lamp of the left headlight; B - vertical line indicating the location of the low beam lamp of the right headlight; C - horizontal line indicating the location of the low beam headlights; D - line indicating the height of the horizontal boundary of the light beams; O - center line; l - distance between low beam headlights; h - distance from the surface of the platform on which the car is installed to the low beam headlights

To complete the work you will need a flat vertical surface (screen) measuring 2x1 m and an assistant (or a load weighing 75 kg).

Sequence of execution

1. We install a fully charged and equipped (spare tire, tool, jack) car on a flat horizontal surface at a distance of 5 m perpendicular to the screen (length - 2 m, height - 1 m).

2. Check and, if necessary, set the required tire pressure (see "Tires - Checking Pressure").

3. Apply markings on the screen (see diagram). Draw the upper horizontal line C at the height of the headlight center from the surface of the platform, the second line D 75 mm below the first. The vertical line O coincides with the plane of symmetry of the car, and lines A and B run parallel to line O through points E, corresponding to the centers of the headlights. The distance / between the low-beam headlights for this car is 936 mm.

4. Set the headlight range control handle to position I (far right) (cm. "Headlight and instrument lighting hydraulic corrector control unit").

5. An assistant sits in the driver's seat or a load is placed on it.

6. Turn on the low beam.

7. Cover one headlight with a piece of cardboard or other suitable object.

8. By turning the adjusting screw located on the rear wall of the headlight unit on the side of the turn signals, we align the upper horizontal boundary of the light beam with the lower line on the screen (EE).
