What is the method for adjusting car headlights?

Car headlights can be adjusted in two ways: 1. Using the buttons inside the car; 2. Through mechanical adjustment on the headlight assembly. The functions of car headlights are: 1. To accurately illuminate the road ahead; 2. To improve safety during night driving; 3. To avoid affecting the vision of oncoming drivers. Precautions for using car lights include: 1. Turn on the low beam when driving at night; 2. Do not use the high beam when a following vehicle is driving close to the vehicle in front in the same direction; 3. When passing sharp turns, slopes, arched bridges, crosswalks, or intersections without traffic lights at night, alternate between high and low beams to signal.

I used to adjust my car headlights myself several times when I noticed they were misaligned. Parking the car on level ground is crucial, and I usually find a blank wall in the parking lot to do this. First, locate the adjustment screws on the headlights—they're typically on the side or back of the light housing under the hood, and you'll need a standard Phillips screwdriver to turn them slowly. When adjusting the height, it's best to turn on the lights 5 to 10 meters away from the wall and observe the position of the beam center. If it's too bright and dazzling for oncoming drivers, lower it a bit; if it's too high and makes the road hard to see, raise it slightly. Remember, the manual provides recommended height values—don't deviate too far to avoid nighttime driving hazards. I once encountered rusty screws and had to apply lubricant to get the job done. After proper adjustment, driving feels much more comfortable with better visibility on the road.

Adjusting the headlight beam mainly relies on two screws: one controls the vertical angle, and the other manages the horizontal direction. These are usually hidden near the headlight assembly in the engine bay. I carefully rotate them using a specialized tool or a regular wrench while observing the light beam's movement from outside the vehicle. This step is crucial, as properly aligning the beam to the center of the road enhances nighttime visibility without disturbing other drivers. For precision, I prefer working at dusk, marking reference lines on a wall based on the vehicle's manual specifications, then gradually fine-tuning the position to ensure even overlap between the left and right lights. After adjustment, a test drive verifies the results, as misaligned beams can cause visual fatigue or blind spot risks.

Light adjustment is crucial for driving safety. If the lights are too high, they can blind other drivers, while lights that are too low may impair your own visibility. Before adjusting, ensure the vehicle is parked on a level surface. Then, open the hood, locate the adjustment points, and slowly turn the screws to correct the alignment. A simple method is to shine the lights against a wall, mark the beam's landing position, and adjust it to the standard height. It's recommended to check regularly or have a professional shop calibrate them to avoid accumulating risks during night driving. If adjustments aren't done properly, seek help from a technician to ensure safety for yourself and others.
