How to Restore Misadjusted Headlights?

[VanDonovan]

After the headlights are misadjusted, there are two adjustment screws at the rear of the headlight assembly—one for adjusting height and the other for width. You can use these screws to adjust the left-right and height alignment. If the light beam is not concentrated, you need to adjust it horizontally until it reaches the proper height. Here are the detailed steps: 1. Alignment Check: Park the car 10 meters away from a wall. Measure the distances from the low beam to the central axis, from the high beam to the central axis, and from the low beam to the ground. Then, move closer to the wall and mark these measurements on the wall. Observe whether the light beam deviates left or right or is too high or low. If the center of the headlight beam does not align with the marked points, it indicates misalignment. You can adjust it by turning the width adjustment screw until the beam center aligns with the marks on the wall. 2. Standard Adjustment: Note that the headlight width is usually preset at the factory, and self-adjustment is not recommended. If there is a slight deviation, minor adjustments can be made. For example, you can slightly shift the right beam to the right, which can improve visibility of the right-side road during low-visibility conditions like rain or fog. However, it is more advisable to visit a 4S shop or repair shop for professional adjustment.
