What is the appropriate height for low beam adjustment?

The height adjustment for low beams is generally set to the 0 initial position. The initial position is the standard low beam position calibrated by the manufacturer during headlight setup. Among the 1-5 adjustment levels for low beams, level 5 provides the farthest light projection. A low beam illumination distance within the range of 30-40 meters is considered normal. First, find a vertical wall and mark a position 40-80 cm above the ground. The marking on the wall should be as large and visible as possible to facilitate adjustment. After marking, park the car parallel to the wall at a distance of 7.6 meters. Turn on the headlights and set them to the low beam position, adjusting the height to the 0 initial position. Ensure the vehicle is unloaded at this time. Then observe whether the light has any lateral deviation or height misalignment. If the headlights are too high or too low, adjust them to the appropriate height by continuously turning the adjustment knob.
Over the years of driving, I've found that adjusting the height of low beams requires careful consideration. Typically, you need to find a dark place, like a garage, park the car about 10 meters away from a wall, and mark a horizontal line at the same height as the center of the headlights. Then, turn on the headlights and use tools to adjust the beam position so it's 1-2 centimeters below that line. This ensures you don't dazzle oncoming drivers at night while still illuminating the road properly. I often check the adjustment after replacing bulbs to prevent the beam from being too low (making distant obstacles hard to see) or too high (causing glare). Safe driving is crucial, so always test after adjustments—fine-tune if needed, and don't skip this step. Regular maintenance can also prevent this issue, and making it a habit leads to more confident driving.
When adjusting the height of low beams, I believe the key is to avoid compromising others' safety. Experience has taught me that the height shouldn't be set arbitrarily: Park on level ground facing a wall, with the car 7-10 meters away, use a ruler to measure the light height and mark it—the center of the beam should be slightly below this mark. Too low, and you won't see potholes, which is dangerous; too high, and you'll blind oncoming drivers at night, which is even riskier. I usually follow the vehicle's manual, but if there isn't one, I use this method—simple and reliable. Maintaining a reasonable beam height protects both yourself and others. Regularly check the lighting effect, and address any issues promptly—don't wait for an accident to regret it. This small adjustment can significantly improve driving safety.
