What is the standard for left and right adjustment of car headlights?

[LeElle]

The standard for left and right adjustment of car headlights is that the low beam cutoff line must be aligned horizontally. The following is an introduction to the methods and precautions for adjusting headlights: Adjustment method: The headlight height adjustment switch uses a roller for adjustment, with numbered gears marked on the roller. The numbers indicate the height of the headlights—the higher the number, the higher the headlight position. Precautions: The height of the car headlight beam is crucial, and correct adjustment is very important. The directional height of the beam not only affects the actual illumination effect but also has a significant impact on the driving safety of both your own and other vehicles. If the car headlight beam is too high, it will not illuminate the ground clearly; if it is too low, the illumination distance will be short.
