The direction of the light beams of the headlights should be such that the road in front of the car is well lit, and the drivers of oncoming vehicles are not blinded when the dipped beam is turned on. Headlights are adjusted by turning screws 3 and 4 (pic. 168), which rotate the optical element in the vertical and horizontal planes. It is most convenient to adjust the headlights with the help of mobile optical devices. If they are not, then the adjustment can be carried out using the screen.
A fully fueled and equipped car with a load of 75 kg on the driver's seat is installed on a flat horizontal platform 5 m from a smooth wall or any screen (plywood shield about 2x1 m in size, etc.) so that the axis of the car was perpendicular to it. Before marking the screen, make sure that the air pressure in the tires is normal, and then rock the car from the side so that the suspension springs are installed.
Drawing on the screen (pic. 169) vertical lines: axial 0 and lines and passing through the points corresponding to the centers of the headlights. These lines must be symmetrical about the center line of the vehicle. At a height corresponding to the distance of the centers of the headlights from the floor, line 1 is drawn and below it by 80 mm line 2 of the centers of light spots. Turn on low beam. Sequentially, first for the right headlight (the left is covered with a piece of cardboard or dark cloth, or turned off), and then for the left (right closed) adjust with 3 screws (see fig. 168) and 4 beams of headlights. For adjusted headlights, the upper border of the light spots must coincide with line 2 (see fig. 169), and the points of intersection of the horizontal and inclined sections of light spots - with lines and
Check if the high beam headlights turn on.
