There are several ways to adjust the light focus of the car LED headlights:
1. Use the adjustment knob:
First, park the car 7.6 meters away from the wall, and then turn on the light.
Adjust the light position according to the position of the light on the wall. Some models have integrated headlight height adjustment knobs. If the car has such a function, the headlight height adjustment knob should be adjusted to "0" before adjusting the headlights.
Measure the following distances of the car headlight position: the distance from the center of the low beam to the center axis of the car (distance A), the distance from the center of the high beam to the center axis of the car (distance B), and the distance from the center of the low beam to the ground (distance C).
Set these standard lines on the wall to facilitate the adjustment of the headlight focus. Before adjustment, hit the headlight on the wall, and then observe whether the headlight is offset or too high or too low, and then adjust it.
2. Install a lens:
The lens can effectively gather the light emitted by the LED headlight and improve the light focusing performance.
It is necessary to remove the vehicle's headlight assembly, use an oven or hot air gun to heat the sealant of the headlight shade, and remove the headlight shade.
Remove the decorative cover on the lens surface of the original headlight, and then remove the old lens. When installing the new lens, be sure to fix the position of the lens and ensure that the lens is tightly connected to the structure of the headlight to achieve the best focusing effect.
3. Use the in-car adjustment function:
Some models have integrated headlight height adjustment knobs in the car, and the height and angle of the headlight can be adjusted directly in the car.
4. Simple judgment method:
Let a person with a height of 180cm stand 7.6 meters in front of the car, and then the low beam should not be higher than the person's hips. If it is too high, then turn the adjustment knob to adjust it.
Through the above methods, car owners can adjust the car's LED headlights by themselves to improve the lighting effect and safety of night driving. However, it is a bit difficult to adjust the car lights by yourself, so car owners can also ask maintenance personnel to help adjust and check the lights when the car is maintained.
