What should I do if the high and low knobs of headlight assembly are broken?

The high and low knob of the headlight assembly of Pacific Auto Network is broken, which can be repaired. Generally, plastic screws accessories can be replaced directly. Headlights illuminate the ground below the front, less than a few meters. Some models support adjusting the lighting angle. By adjusting the angle upwards, the lighting can be farther, and you can get a better view by driving at night.

The state has a series of regulations on the lighting height in car headlights, which are complicated. In short, it is measured by the simplest and most effective method: taking the rear of the front car 4 to 5 meters away as the reference object, the tangent line of the headlights of this car is based on the highest illuminance on the windshield of the front car, and no minimum requirements are made. However, I believe no one wants the light angle to be too low to see the road. The recommended height is basically suitable for the height of the rear license plate. The purpose of this is not to illuminate the front car and avoid the influence of the high beam. Similarly, aim at the front of the front car, and the tangent line cannot exceed the lower edge of the front windshield. After the approximate height is determined, just aim at the tangent of the left and right headlights in the way mentioned above.

Adjust the headlight height. First, find a flat wall to ensure the level of the road. Park the vehicle vertically at a distance of about 3 meters. Turn on the headlights. Assuming that the headlight on the right side has just been replaced, we can see that its lighting height is obviously higher than that on the left side. The tangent lines of the headlights are flush on both sides. Therefore, if there is no problem with the height of a headlight, just fine-tune the headlight on the right.
