How to Adjust Car Headlights Correctly?
2 Answers
Correct method for adjusting car headlights: 1. Park the vehicle facing a wall at a distance of about 10 meters, observe the height of the left and right lights, and use tape or other markers for measurement, comparison, and adjustment if necessary; 2. After adjusting the horizontal alignment of the headlights against the wall, find a reference point on the vehicle for comparison, adjust the height of the headlights at a distance of about ten meters, and adjust the horizontal position when closer; 3. After adjustment, observe from both inside and outside the vehicle, or simulate the height from the opposite direction for verification, repeatedly adjust until appropriate. High beams usually do not require adjustment. Car headlights, also known as car front lights or car LED daytime running lights, serve as the eyes of the car. They not only relate to the external image of the car owner but are also closely linked to safe driving at night or under bad weather conditions.
Adjusting car headlights is something I'm very familiar with. Once I spent a whole night doing it myself before figuring out the trick. The correct method involves three steps: First, find a flat area with a vertical wall about 5-6 meters away from the front of the car, then turn on the low beams. Next, stick a piece of tape on the wall to mark the center height of the headlights, manually turn the adjustment bolts at the back of the headlights to make the light beam fall about 10 cm below the tape—this ensures you don't blind oncoming traffic while still illuminating the road properly. For horizontal adjustment, make sure the light beams from both headlights are symmetrically aligned. Finally, remember to take a test drive at night, especially on slopes—if the beams are too high, you'll need to readjust. Professional headlight alignment at a shop usually costs just a few dozen bucks, saving you time and effort.
