How to Adjust Car Headlights for Focused Beam?

[McMatthew]

Due to inherent design issues or various factors during modification, LED headlights may experience severe light scattering and lack of focus. Therefore, it is necessary to adjust the beam angle to meet the driver's safety requirements. The adjustment steps are as follows: 1. First, park the car 7.6 meters away from a wall, turn on the headlights, and then adjust the beam position based on the light pattern on the wall. Some vehicle models come with an integrated headlight height adjustment knob inside the car. If this feature is available, set the headlight height adjustment knob to the "0" position before adjusting the headlights. 2. Next, mark reference lines on the wall. Measure the distance from the center of the low beam to the vehicle's central axis, the distance from the center of the high beam to the vehicle's central axis, and the distance from the center of the low beam to the ground beforehand. 3. Finally, adjust the corresponding adjustment knobs located at the back of the headlights to fine-tune the beam position. The specific parts to adjust and the tools required may vary depending on the vehicle model. Before making adjustments, project the headlights onto the wall and observe whether the beam is misaligned, too high, or too low.
