The fog light on the Excelle is the light located below the rear lamp. The functions of the fog light are: 1. The front fog light is used to improve illumination when the road ahead is unclear and can alert oncoming drivers; 2. The rear fog light helps vehicles behind to spot the car in low visibility conditions. Taking the 2021 Buick Excelle as an example, it is a compact car with body dimensions of: length 4609mm, width 1798mm, height 1486mm. 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.

The front fog lights of the Excelle are generally located directly below or slightly inward from the headlights, while the rear fog lights are positioned within the taillight assembly, resembling circular LED clusters or bulbs. Having driven the Excelle for several years myself, I recall how particularly useful the fog lights are when activated, especially during foggy conditions or heavy rain when visibility is poor—they enhance the vehicle's recognizability and help prevent rear-end collisions. To locate them, it's quite simple: look for the fog light icon switch on the steering column or dashboard control stalk, then give it a gentle twist. Don’t forget to check if the bulbs are damaged or covered in dust, which could affect brightness. For routine maintenance, I recommend regularly wiping the fog light covers to maintain light transmission. If the lights fail to illuminate, it might be due to a blown fuse or poor wiring contact. You can attempt replacing the fuse yourself, but if that doesn’t resolve the issue, it’s best to visit a professional repair shop.

To turn on the fog lights of my Excelle, I usually start by turning the ignition key to start the vehicle, then look for the knob or button with the fog light symbol near the center console, typically located in the lighting control area. After pressing or rotating it, both the front and rear fog lights will illuminate, like a pair of small yellow lights below the front bumper and a striking red dot at the rear. Turning on fog lights can be a lifesaver in severe weather—I've experienced how they improve visibility on foggy highways, preventing collisions with other vehicles. However, it's important not to misuse them; there's no need to turn them on during clear daytime as they can be blinding and hazardous. If the fog lights aren't working, first check if the switch is stuck or if the bulb is old. Use a phone flashlight to inspect for simple issues, then consider replacing the bulb or seeking professional repair to ensure safety.

I believe the key function of Excelle's fog lights lies in safety, especially during hazy weather or rainy days with slippery roads. When activated, a pair of bright yellow lamp units illuminate at the front, typically embedded below the front bumper, while small red lights integrated into the taillights are activated at the rear. I always remember to turn them on while driving because they penetrate fog to make my vehicle more visible to others, reducing accident risks. Traffic regulations mandate their use in low visibility conditions. If I notice insufficient brightness in daily use, I first consider external dirt blockage or bulb failure, promptly cleaning the lens covers or replacing bulbs to maintain performance.

Many people confuse the fog lights and daytime running lights on the Excelle. Fog lights are primarily used in special weather conditions. They are located in the lower area of the vehicle body, with a yellow light in the center of the front bumper, while at the rear, they are part of the taillight assembly and clearly marked. While driving, I've noticed that beginners often overlook the right time to use them—fog lights should only be activated in foggy conditions, not for daily illumination. If the fog lights fail to work, it might be due to a short circuit or a blown fuse. I recommend first checking the fuse box and replacing the corresponding fuse. If that doesn't help, seek professional assistance. Remember, proper usage enhances safety and saves energy.

For the of the Buick Excelle's fog lights, I usually wipe the lamp covers to remove dust and debris during car washes to prevent reduced brightness. Normally, fog lights are located in the embedded holes below the headlights at the front and on the sides of the taillight assembly at the rear. During inspection, you can use the manual switch to test if the response is sensitive. If flickering or no light is observed, it might be due to oxidized lamp sockets or voltage issues—simple cleaning can be done by yourself, but complex situations require a repair shop. Additionally, during foggy conditions, I always check if they are functioning properly to ensure clear driving visibility and reduce risks.
