What number should the headlight height be adjusted to?

Headlight height is generally set to the O-level position as the initial setting. Here is some relevant information about car headlights: 1. Introduction to car headlights: Car headlights, also known as car front lights or car LED daytime running lights, serve as the 'eyes' of a car. They not only affect the owner's external image but are also closely related to safe driving at night or under bad weather conditions. 2. The role of light adjustment: It allows the car's lights to maintain an appropriate height at all times, facilitating nighttime driving and adapting to different road conditions. 3. The importance of light adjustment: The more passengers in the back seats, the lower the rear of the car sinks, which causes the front of the car to rise accordingly. This raises the height of the headlights, potentially dazzling drivers of oncoming vehicles and distracting them, which can easily lead to traffic accidents.
I've been driving for decades, and the headlight height adjustment is something to be really careful about. The higher the number, the lower the beam, and vice versa. Generally, setting it to 0 or 1 when the car is unloaded is best—it illuminates the road without dazzling others. But I usually set it to 2, which is just right—not too high or too low. If the trunk is fully loaded or the back seats are occupied, causing the rear to sag, you should adjust it higher, like 0 or 1, otherwise the beam will be too angled and visibility will suffer. I recommend testing it against a wall at night—the light spot should land about 20 meters ahead, not exceeding 50 meters. Forgetting to adjust it properly can lead to accidents, like driving too fast on mountain roads with poor visibility around bends, or getting honked at by oncoming drivers. Safety first. It's best to check the headlight alignment every six months—don’t skip it for convenience.
