How to Adjust the Headlights of Buick Excelle?
2 Answers
Buick Excelle headlights can be adjusted as follows: There are two hex screws behind each headlight. The two screws facing upward are for adjusting the height, while the two screws facing inward are for adjusting the left-right angle. Car headlights, also known as car front lights or LED daytime running lights, serve as the 'eyes' of the car. They not only affect the owner's external image but are also closely related to safe driving at night or in bad weather conditions. The Buick Excelle is a premium mid-size sedan under SAIC-GM, with dimensions of 4587mm in length, 1798mm in width, and 1463mm in height, and a wheelbase of 2640mm. The vehicle is equipped with two powertrain options: a 1.3T dual-injection turbocharged engine paired with a 6-speed DSS intelligent dual-clutch transmission, and a 1.0T dual-injection turbocharged engine paired with a 6-speed DCG intelligent dual-clutch transmission.
I remember my Buick Excelle's headlights were aimed too high, so I tried adjusting them. Usually, if there's a height adjustment knob inside the car, it's located on the left side of the steering wheel or on the dashboard. Turning it can adjust the beam height, making it convenient for real-time adjustments while driving. If there's no such button, you'll need to do it manually: first, open the hood, then locate the vertical and horizontal adjustment screws at the back of the headlight assembly—they're typically Phillips-head screws—and slowly turn them with a screwdriver. Park the car on a flat surface, turn on the headlights about 5 meters away from a wall, and the center of the light beam should align at a height of 0.5-0.8 meters. If it's too high, it can blind oncoming drivers and cause accidents; if it's too low, it won't illuminate the road ahead clearly. When adjusting, do it gently to avoid stripping the screws. If you're unsure, it's best not to force it and instead take it directly to a 4S shop for a professional to handle. After all, improperly aimed headlights can seriously affect nighttime safety and increase fuel consumption. Regularly checking and adjusting them is a good habit, especially after long trips.
