How to Adjust the Focus of LED Headlights on a Car?

[GenevieveRose]

Due to design reasons or various factors during modification, LED headlights on cars may suffer from severe light dispersion and lack of focus. Therefore, it is necessary to adjust the angle of the lights to meet the safety needs of the driver. Here is the adjustment tutorial: 1. First, park the car 7.6 meters away from a wall, then turn on the headlights. Next, adjust the light projection position based on the light's position on the wall. Some car models are equipped with a headlight height adjustment knob inside the vehicle. If this function is available, set the knob to the "0" position before adjusting the headlights. 2. Then, mark standard lines on the wall. Measure the distance from the center of the low beam to the car's central axis, the distance from the center of the high beam to the car's central axis, and the distance from the center of the low beam to the ground beforehand. 3. Finally, adjust the corresponding adjustment knobs behind the headlights to align the light position. The parts that need adjustment and the tools required vary by car model, so adjustments should be made according to the specific model. Before adjusting, project the headlights onto the wall and observe whether the light is misaligned, too high, or too low.
