How to Adjust the Headlights of a Buick Excelle?
3 Answers
The method to adjust the headlights of a Buick Excelle is as follows: There are two hex socket screws behind each headlight. Two of them face upward for adjusting the height, and the other two face inward for adjusting the left-right angle. Taking the 2021 Buick Excelle as an example, it is a compact car with body dimensions of 4609mm in length, 1798mm in width, 1486mm in height, and a wheelbase of 2640mm. The 2021 Buick Excelle features a MacPherson strut front suspension and a multi-link independent rear suspension. It is equipped with a 1.3T turbocharged engine, delivering a maximum horsepower of 163PS, a maximum torque of 230Nm, and a maximum power of 120kW, paired with a 6-speed automatic transmission.
My experience with adjusting the Buick Excelle's headlights is to first locate the hood release handle inside the car, usually found under the steering wheel. Pull it to open the hood and secure it properly. Then, at the back of the headlight, you'll see a screw with a cross slot, typically used for adjusting the height—some cars also have screws for horizontal adjustment. I prepare a small Phillips screwdriver, insert it into the screw, and turn it counterclockwise to raise the beam or clockwise to lower it. This ensures the lights don't blind other drivers at night while still providing enough illumination to see the road clearly. It's best to adjust the lights in a garage or a dark area with the lights on, testing the beam position against a wall. The ideal height is when the center of the light spot at about 10 meters from the front of the car aligns with the height of the headlights. The first time I did this, I rushed and turned the screw too much, loosening it and causing the headlight to tilt. I had to re-secure it. I recommend turning the screw slowly and checking the adjustment multiple times—safety first to avoid accidents. After finishing, remember to close the hood and test the effect.
I believe adjusting headlights is crucial for safety, because misaligned beams on a Buick Excelle could blind oncoming drivers at night and cause accidents. As a frequent driver, my method is: After opening the hood, locate the small adjustment screw near the headlight assembly inside the front bumper, then gently rotate it with a hand tool to alter the beam angle. Remember that vertical adjustment mainly prevents glare, while horizontal adjustment corrects the coverage range. I've tested this in a garage by turning on the low beams against a wall - the light pattern should align with a horizontal line. If set too high, it dazzles others; too low compromises your own visibility, which poses risks during long drives or in fog. Also, avoid excessive force to prevent damaging the screw mechanism - Buick parts can be troublesome to replace. For best results, perform adjustments on level ground when parked to ensure road safety without creating hazards.
