The LED headlight bulb is generally designed according to the position of the original Halogen lamp light source. After it is installed on the car, please drive the car 10-20 meters away from the white wall to check whether the light on the wall is appropriate. If you have no experience in installing headlights, you can first check the light shape of the original headlight bulb on the wall before replacing it. After installing the LED headlight bulb, compare the effect of the new headlight with the pictures taken earlier. Do you need to make adjustments based on the comparison of the front and rear light shapes. It is generally recommended to make adjustments with experienced car repair technicians.
