Why is the headlight adjustment screw not responding?

[DianaMarie]

The following are the reasons why the headlight adjustment screw is not responding and the corresponding solutions: 1. Incorrect positioning after an accident, requiring repositioning. 2. The bulb's original angle is incorrect, making adjustment impossible; in this case, replace the bulb. Below are the methods for adjusting headlights: If the headlight beam is too high, even if there is a headlight height adjustment knob inside the car, setting it to the initial "0" position will not help. In this case, we can adjust the height by turning the corresponding adjustment knob located at the back of the headlight. The parts that need adjustment and the tools required vary depending on the vehicle model, so it is necessary to determine based on the specific model. Common tools include hex wrenches and Torx sockets. Next, park the car 7.6 meters away from a wall, turn on the lights, and then adjust the beam position based on the light's position on the wall. If there is a headlight height adjustment knob inside the car, first set it to the "0" position.
