What does turning the headlights clockwise do?
2 Answers
Here is a detailed introduction about adjusting headlights clockwise: 1. Lowering headlights clockwise: Turning the adjustment screw clockwise with a screwdriver (i.e., rotating it to the right) will lower the headlight beam. Conversely, turning it counterclockwise will raise the beam. The headlight adjuster is designed to correct deviations in the headlight's illumination direction caused by factors such as vehicle load, prolonged vibration, or varying road conditions. Its function is to restore the headlights' illumination direction from deviated positions back to the standard direction, thereby improving lighting effectiveness. 2. Additional information: Headlights generally refer to high beams and low beams. They are primarily used for illumination during nighttime or in weather conditions requiring visibility, such as heavy fog or rain, and include both high and low beams.
Last time I adjusted my headlights myself, turning the adjustment screw clockwise was actually quite simple—it makes the beam shift to the right. If you stand in front of the car facing a wall, each turn moves the beam slightly to the right, while turning counterclockwise shifts it left. But don’t just tweak it randomly—do it against a white wall, preferably at night. Back then, I used a tape measure to adjust, ensuring the driver’s side light was 5–7 cm lower than the right side for the correct standard. This way, you get good visibility at night without blinding oncoming drivers. For precise adjustments, though, it’s best to visit a 4S shop—they use a level and beam alignment templates for professional results. Oh, and some cars have two adjustment holes under the hood, so make sure you find the right screw.
