Adjusting the direction of the headlight beams

We adjust the direction of the headlight beams on a fully fueled and equipped car, with normal air pressure in the tires. We install the car on a flat horizontal platform at a distance of 5 m from the screen (you can use a garage wall, a sheet of plywood or hardboard measuring 1x2 m). Draw a horizontal line 1 on the screen at a height equal to the distance from the center of the headlights to the floor. Draw a parallel line 2 below it by 65 mm.

Draw a vertical center line on the screen 0 (the distance from it to the center of the left and right headlights should be equal) and lines corresponding to the centers of the headlights (AE and BE).

Set the headlight range control switch to position "0" (one driver or a driver with a passenger in the front seat) and turn on the headlights. We close one of the headlights with an opaque material.

When adjusting, the upper limit of the light beam must coincide with the lower horizontal line (see fig.), and the point of the beam break (point of intersection of the horizontal and inclined sections of the luminous flux) - with a vertical line corresponding to the center of this headlamp.

Similarly, we adjust the direction of the light beam of the other headlight.



Scheme for adjusting the direction of headlight beams




Arrangement of light beam direction regulators on the headlight housing of a car with a hatchback body: 1 - light beam regulator in a vertical plane; 2 - light beam regulator in the horizontal plane



Location of light beam direction regulators on the headlight housing of cars with sedan and station wagon bodies: 1 - light beam regulator in the horizontal plane 2 - light beam regulator in the vertical plane



We adjust the direction of the headlight beam by rotating the regulators with a Phillips screwdriver.


Similarly, we adjust the direction of the light beam of the other headlight.

Adjustment of the beams of light of fog lamps is carried out under the same conditions as when adjusting the headlights (see above). We measure the distance between the centers of the fog lights and the distance from the surface of the site to the center of the fog lights. We draw lines on the screen and draw another horizontal line below the height line of the center of the fog lamps by 50 mm.

Adjustment is carried out from under the bumper of the car. Turning the headlamp adjustment screw with a Phillips screwdriver, we bring the upper horizontal border of the headlight beam to the height line of the center of the fog lamps.



Screen layout for adjusting the fog lights: A - the distance between the centers of the fog lights; H - the height of the center of the fog lights on the car



Change the direction of the fog light beam by turning the adjusting screw with a Phillips screwdriver (for clarity shown on the removed headlight).
