Does turning the headlight clockwise adjust it higher or lower?

Turning the headlight clockwise adjusts it lower, while turning it counterclockwise adjusts it higher. Below are specific instructions for adjusting car headlights: 1. Measurement method: Find a level ground, face a white wall, and park the headlights 25 feet away from the wall. 2. Low beam adjustment: Turn on the low beams before adjusting, and use a Phillips screwdriver to adjust the height. 3. High beam adjustment: Turn on the high beams and use a hex socket to adjust the height and left-right alignment screws for the high beams. Here is additional information: A car headlight adjuster is designed to correct the direction of the headlight beam, which may deviate from the standard direction due to factors such as vehicle load, prolonged vibration, or uneven road conditions. The adjuster's function is to restore the headlight's beam direction from the deviated position back to the standard direction, thereby improving the lighting effect.
I've found that turning the headlights clockwise usually lowers the beam height to avoid dazzling oncoming vehicles at night. With years of auto repair experience, I recommend starting by checking the vehicle's adjustment screws—turning clockwise tilts the headlight downward, focusing the light closer to the road surface. This enhances near-range illumination but reduces long-distance coverage. This adjustment may be necessary when a vehicle is heavily loaded or on uneven roads, causing automatic headlight position changes. I've encountered many owners who adjusted incorrectly and faced traffic fines. The correct method is to test the headlight cutoff line height on a flat surface facing a wall to ensure safety. Counterclockwise adjustment raises the beam, suitable for mountain roads but should be used cautiously to avoid affecting others. Regular maintenance checks on the adjuster are also essential to prevent malfunctions.
Last week, I adjusted my car headlights myself and found that turning the adjuster clockwise significantly lowered the beam, effectively reducing the height. This design primarily minimizes the risk of dazzling oncoming drivers and prevents accidents. As an average car owner, I used a simple method to test: at night, I found a wall, turned on the low beam mode to mark the light position, then turned the screw clockwise to observe the light line descending. If adjusted too high, turning it counterclockwise can restore it. By the way, sometimes dim headlights are due to bulb or wiring issues rather than incorrect adjustment direction, such as a blown fuse—checking these possibilities first can save hassle. Maintaining proper headlight height is crucial for comfortable and safe nighttime driving.
