Checking the installation of headlights (VW Golf 1)

After replacing the headlight insert, you need to check whether the light beam is directed correctly. This is most accurately done in a workshop; a special measuring device is used for this. There are also auxiliary methods with varying accuracy.



Place the car at a right angle at a distance of 5 m from a light wall. Install the new headlight at the same height as the headlight that was not changed. However, lateral adjustment cannot be made this way.

Using a measuring device, precise adjustment is made; the breaking points need to be drawn on the garage wall (from these points the rays of light rise 15 degrees up and to the right). To do this, stop the Volkswagen at the garage door. Later, with the car in the same position, you can also check the lateral direction of the light beams.



Draw precise auxiliary lines on the wall; the wall must have at least 9 m of flat surface. These lines are visible in the picture above. Some preparatory work will be required. You can also glue crepe tape in the appropriate places on the wall (or tape) and then draw.

Auxiliary lines for installing headlights

Stop the machine exactly 5 m from the wall, with the front side of the machine parallel to the wall.

Measure the height of the center points of the headlights on both sides; mark on the wall (dimension "d").

At a distance of 50 mm from this line draw line "A" on the wall. This is the slope of the low beam at a distance of 5 m.

Determine the center of the car through the rear window by eye; the assistant should draw a vertical line "M" on the wall exactly in the middle.

Measure the distance from the center of the car to the center point of the low beam headlight - dimension "a"; to the left and right of the line "M" put aside the dimension "a" and draw a cross.

The low beam break points should be adjusted using these crosses.

Only for vehicles with additional high beam headlights: the points at height "d" and on line "F" are connected together.

The original can be seen on the portal [VWManual]

If there are additional high beam headlights, then draw crosses along the size of "f" between the middle of the car and the middle point of the headlight to the right and left of "M" on line "F".

Using these crosses, you need to adjust the high beam headlights.

The locations of the mounting screws are shown in the illustrations.
