What are the methods for adjusting car lights?

Methods for adjusting car headlights: 1. Automatic adjustment: Some models feature automatic headlight height adjustment. 2. Manual adjustment: Adjust the height by turning the corresponding adjustment knobs located behind the headlights. The position of these knobs and the tools required vary by model, commonly including hex wrenches and star sockets. Park the car 7.6 meters away from a wall and adjust based on the light's position on the wall. 3. In-car headlight height switch adjustment: Typically, the headlight height adjustment switch uses a numbered wheel, where higher numbers indicate higher headlight positions. Choose the appropriate setting based on actual conditions, as vehicle load can affect the adjustment.
I've been driving for many years and often adjust the headlights myself. I find headlight adjustment quite simple. There are a few main methods: First, you can use manual adjustment screws, usually hex screws located under the headlight cover or hood. Turning clockwise raises the beam, while counterclockwise lowers it. Before adjusting, park on a flat surface facing a wall, turn on the lights, and mark the center point on the wall as a reference line. This makes it easy to see if the beam height is appropriate. If the lights are too dim or too bright, it can easily affect nighttime driving safety and cause accidents. Another method is adjusting the left-right angle to prevent dazzling other vehicles, usually controlled by a small knob. I also regularly check if the lights are aligned, as bumpy roads may loosen the adjustments. Of course, if the lights are consistently misaligned, it might be a suspension system issue, in which case it's best to visit a professional repair shop.
As an enthusiast who loves tinkering with my car, I often adjust the headlights myself. The core method involves manual adjustment: locate the adjustment hole or knob near the headlight, and use a regular wrench or professional tool to turn it, which changes the height and tilt angle of the light. It's best to test it at night in front of the garage, drawing a horizontal line on the wall as a reference. Additionally, some models have an automatic headlight adjustment feature that uses sensors to detect terrain changes and adjust automatically, which is convenient but less precise than manual adjustment. Improper adjustment can waste bulb life, so I frequently check if the screws are corroded and add lubricant if necessary. If the light is scattered or not focused properly, try replacing the bulb. DIY adjustment tools are cheap to buy online, but avoid using excessive force to prevent damaging the wiring, and always take a test drive after adjustment to confirm the effect.
