How to Adjust the Vertical and Horizontal Alignment of Car Headlights?
1 Answers
Car headlight vertical and horizontal adjustment methods are as follows: 1. Vehicle light adjustment typically involves the left-right and up-down alignment of low beams. This can be done using the adjustment knobs located at the rear of the headlight assembly, allowing owners to adjust the lights themselves with appropriate tools. 2. Open the engine hood, locate the adjustment knobs at the rear of the headlight assembly, and use the corresponding tools for adjustment. Before adjusting, determine whether the knob controls left-right or up-down movement. 3. Park the vehicle facing a wall at a distance of approximately 10 meters. Observe the height of both headlights and, if necessary, use tape or other markers for measurement, comparison, and adjustment. 4. After adjusting the horizontal alignment of the headlights against the wall, find a reference point on the vehicle for comparison. Adjust the headlight height at a distance of about 10 meters, and adjust the horizontal position when closer. 5. After completing the adjustments, observe the lights from both inside and outside the vehicle. You can also simulate the height from the opposite direction for verification. Repeat the adjustments until satisfactory. High beams usually do not require adjustment.
