Headlight alignment is the process of adjusting the angle of your headlights to ensure that they are pointing in the correct direction. This is important for both safety and visibility. Properly aligned headlights will help you see the road ahead clearly and will also help other drivers see you.
There are a few different ways to check your headlight alignment. One way is to use a tape measure. Park your car on a level surface and measure the distance from the ground to the center of each headlight. The distance should be the same for both headlights.
