Adjusting the headlight light
Screen layout diagram for adjusting the light of the headlights: A - vertical line indicating the location of the center 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/high beam headlight lamps; D - line indicating the height of the rise of the horizontal border of the light beams; O - center line; I is the distance between the low beam lamps of the headlights; h - the distance from the surface of the site on which the car is installed to the center of the low beam headlights
To complete the work you will need an assistant, as well as:
- - a flat horizontal area (preferably near the wall of a house, fence or gate);
- - tape measure 5 m long;
- - a sheet of cardboard (to cover the headlight when adjusting).
It is advisable to make adjustments in the dark.
The vehicle must be in running order (fully fueled and without additional cargo).
Since it is not easy to find a suitable surface as a screen, it is easier to use a plywood board measuring 1x2 m with markings applied to it.
In this case, it is necessary to prepare a stop or stand to install the shield vertically.
We install the car on a flat horizontal platform perpendicular to the surface selected as the screen and at a distance of 5 m from it.
Mark the screen according to the picture.
The necessary measurements can be taken using a tape measure.
Check the tire pressure and, if necessary, adjust it to normal.
Turn the drive knob for the electric headlight adjustment to position 0, which corresponds to the minimum vehicle load.
The assistant sits in the driver's seat.
Having turned on the low beam of the headlights, we cover one of the headlights, for example the right one, with a sheet of cardboard.
By rotating the adjusting screw 1 of the left headlight unit, we bring the horizontal line of the light beam to line “D” on the screen.
Through the hole in the body panel, using a 6 mm hex key, rotating adjusting screw 2, align the bend of the light beam boundary with line “A”
