Headlight beams — adjustment (Opel Ascona C)

1. Correct headlight beam adjustment is very important, not only because of its impact on your safety, but also because of its impact on other drivers. Correct adjustment of the headlight beam can only be achieved using special optical equipment, and any adjustments made without the use of special equipment should be considered by you as temporary measures only.

2. To make a temporary adjustment, place the vehicle on a level surface approximately 3 meters from a vertical wall or a piece of board positioned strictly vertically. The wall or board must be perpendicular to the center line of the vehicle and the vehicle must be normally loaded. Also check that your tires have the correct pressure.

3. Draw a vertical line on the board that coincides with the central axis of the car.

4. Rock the car vigorously several times to level it, then carefully measure the height from the ground to the center of the headlight beam.

5. Draw a horizontal line on the wall or board at the same height as the centers of the headlights, and on this line place a cross on each side of the center line, at the same distance as the centers of the headlight beams.

6. Now find the controls on each headlight. Each headlight has two of them, located diagonally from each other (see photo 31.6).





7. Turn on the headlights fully and, using the controls, adjust each headlight so that the beam is positioned directly under the corresponding cross on the wall or board.

8. Rock the car again a few times to make sure the headlight beams are in the correct position. At the same time, check the operation of the high beam switch to make sure that the beams are deflected slightly to the side and downward. When finished, turn off the headlights.

9. Have your setup checked by professionals as soon as possible.
