How to adjust and test beams of headlights?
1. Beam adjustment and testing should be performed before a screen in a dark environment, or with the aid of a measuring instrument. The site for adjustment and testing should be level, with the screen kept perpendicular to the ground. The car should be operated by a driver without further load on board.
2. The beam radiation direction is expressed as Deviation I. This deviation refers to the movement distance of the cut-off line (the deflection angle) or the beam center along horizontal (h-h) direction or vertical (left-left or right-right) direction on a screen 10m (dam) away from the light source during adjustment.
3. Adjustment and testing on the screen. Park the car in front of the screen and keep the headlight perpendicular to the screen. The reference center of the headlight in question should be 10m from the screen, and the h-h line on the screen should be on the same height above aground as the reference center of the headlight. Measure the deviation value of horizontal and vertical beams cast from left, right, low-beam, and high-beam positions respectively.
4. Adjustment and testing with a measuring instrument. Park the car at a specified distance from the measuring instrument. On the screen of the instrument, read the deviation of horizontal and vertical beams cast from left, right, low-beam, and high-beam positions respectively.
