How to Adjust Car High and Low Beams?
4 Answers
There is a light control knob on the left side of the steering wheel. The knob will indicate which direction to turn for the low beams. Simply turn the knob according to the markings to activate the low beams. The lever on the left side of the steering wheel: push it forward to flash the high beams once, and pull it backward to keep the high beams on continuously.
Every time I adjust my headlights, I start by parking about 10 meters away from a wall. Open the hood and locate the two screws behind the headlight—the vertical one adjusts up and down, while the horizontal one adjusts left and right. Use a Phillips screwdriver to turn them carefully without applying too much force. When adjusting, focus on the light pattern on the wall: the low beam should be positioned lower, with the upper limit of the light pattern not too high to avoid dazzling other drivers; the high beam center should align perfectly straight. Turn the screws step by step, testing the lights after each small adjustment until the beam position is just right. Remember to check the actual effect during nighttime driving to ensure the road is properly illuminated. If not adjusted correctly, lights set too high can blind oncoming traffic, increasing accident risks, while lights set too low may fail to illuminate the road ahead sufficiently. Last time, I adjusted them too low, making nighttime highway driving extremely dangerous—I had to redo it later. For beginners, I recommend recording the initial position with a smartphone video before making gradual adjustments—don’t rush. Regular checks are also crucial, as vibrations can loosen the screws; inspecting every six months is ideal. Safe driving relies on these small details.
As an experienced driver, headlight adjustment is a fundamental skill. Park on a level surface with the front of the car facing a wall 5-10 meters away. There are adjustment points at the back of the headlights—the vertical knob controls the up-down position, while the horizontal knob adjusts the left-right tilt. Use a screwdriver or professional tool to gently turn them. Adjustment principle: The low beam should project straight downward, not exceeding half the height of the headlight position; the high beam should focus directly forward to prevent scattering. During testing, turn off other light sources to observe the light pattern. After adjustment, take a night test drive to verify the effect. Improper lighting may lead to fines or collisions—I once neglected this and nearly caused an accident. Now I check it during annual maintenance. Simple steps, but they enhance driving safety.
Adjusting the high and low beams is quite simple. Park 5-10 meters in front of a wall. Open the hood and locate the screws behind the headlights—one adjusts up and down, the other left and right. Turn the tool slightly and observe how the light spot moves on the wall. The low beam should be low but not too high; the high beam's center should be aligned. Test a few times until it's just right. Once done, check the actual visibility by driving at night. Avoid unnecessary adjustments to prevent misaligned lights from affecting others or yourself. For first-time adjustments, refer to the owner's manual or online videos and take your time.
