Where is the position of the headlight vertical and horizontal adjustment screws?
2 Answers
The position of the headlight vertical and horizontal adjustment screws is located at the rear of the headlight assembly. The standard for adjusting car headlights is: 1. Drive the car to a flat and open road surface; 2. Turn on the headlights and adjust the low beam projection point to about 30 meters from the car, ensuring the two projection points overlap; 3. Adjust the high beam projection point to be parallel to the ground. The maintenance methods for car headlights are: 1. Regularly check the sealing of the headlights, and replace the sealing ring between the lens and reflector if damaged; 2. Clean the reflector regularly, and replace it if it turns black or the light intensity decreases; 3. Regularly remove dust and stains from the bulbs.
I remember that the screws for adjusting the height and left-right position of the headlights are usually hidden in the engine compartment, at the rear or side of the headlight assembly. After opening the hood, locate the headlight assembly, and you'll find several adjustment points: one vertical screw for height adjustment and another horizontal screw controlling the left-right swing. Most models can be easily adjusted with a Phillips screwdriver or socket wrench, but some newer cars might have plastic covers that need to be pried open first. It's recommended to perform the adjustment at night on a flat surface, aiming at a white wall to observe the light cutoff point—this prevents the beams from shining too high and blinding oncoming traffic or too low and reducing visibility. From personal experience, avoid turning the screws too forcefully; small, gradual adjustments work best. If the headlights are misaligned, it can compromise driving safety by obscuring obstacles or causing glare-related accidents. In short, consulting the owner's manual before making adjustments is the safest approach to avoid damaging the components.
