How to adjust the left and right of the Lingdong car lights?

First, open the front hood and locate the adjustment hole above the headlight position. Turn on the headlights and aim them at a flat wall, then adjust the screws up and down. Below is more information about car lights: 1. Lighting lamps: Lighting lamps should provide good illumination while minimizing glare. For headlights, both high beam and low beam modes are used to balance these two requirements. 2. High beam: This is a long-distance illumination beam used when there are no oncoming vehicles or when not following other cars. It is generated by the main filament with higher power located at the focal point of the reflector, with the beam direction approximately horizontal. It is usually specified that the maximum luminous intensity of a single lamp should not be less than 20,000 candelas. To ensure driving safety, the illumination distance of the high beam (the distance to detect and recognize obstacles) should be greater than the braking distance required for timely stopping. 3. Low beam: This is a short-distance illumination beam used when encountering oncoming vehicles or following other cars. It is generated by a secondary filament with lower power, which is offset from the focal point and optical axis of the reflector, causing the beam to project downward. To limit the beam above the horizontal direction, a metal light shield is usually installed below the secondary filament, creating a sharp light-dark transition on the vertical screen. When encountering oncoming vehicles, the driver's eyes are located in the dark area of the low beam pattern, thereby minimizing glare.
I remember learning how to adjust the left-right direction of my Lingdong car's headlights right after buying it, and the process was quite simple. After opening the hood, I looked for the screws at the back of the headlight assembly—usually there are two, one for adjusting up-down and another for left-right. Using a standard Phillips screwdriver I had at home, I gently turned the screw marked for left-right (or horizontal) adjustment. For precision, I parked the car on level ground at night, about 5 meters from a wall, turned on the low beams, and first marked the center point on the wall with tape. When turning the screw, I noted that clockwise rotation slightly moved the beam to the right, while counterclockwise moved it left. The goal was to align the beam slightly toward the driver’s side to avoid dazzling oncoming traffic. After adjusting, I repeatedly turned the lights on and off to check the effect and found the light distribution much more even, making nighttime driving safer. A reminder: don’t overtighten the screws to avoid stripping them. Also, headlight alignment can be affected by bumps, so it’s advisable to check them during every maintenance service.
From my frequent experience helping friends adjust headlights, the left-right adjustment on the Hyundai Elantra isn't too difficult. After opening the hood, I locate the plastic cover on the headlight module, remove it to reveal two screws: the vertical one adjusts height, while the horizontal one controls left-right alignment. Using a standard screwdriver, I gently turn the horizontal screw in small increments (about half a turn each time) while observing the beam pattern. For testing, I prefer completely dark locations like garages, projecting the light onto a wall to adjust the angle, ensuring the left-right coverage stays within standard width. If the beam leans too far left, it may fail to illuminate pedestrians on the right; excessive rightward tilt could dazzle oncoming drivers. Avoid using oversized tools to prevent damaging components. After adjustment, test driving shows significantly improved visual stability. Always note the final screw positions for future maintenance. If screws resist turning, it might indicate aged components requiring replacement.
