What is the purpose of fog lights?
2 Answers
Fog lights serve the following purposes: 1. Front fog lights are installed on the front of the car at a slightly lower position than the headlights, used to illuminate the road during rainy or foggy weather. Due to low visibility in foggy conditions, the driver's line of sight is limited. Yellow fog lights have strong light penetration, which can improve visibility for the driver and other road users. 2. Rear fog lights are designed in red to serve as a warning, alerting vehicles behind to maintain a safe distance. Precautions for using fog lights: Fog lights are suitable for severe weather conditions such as heavy rain, fog, snow, or dust. The visible range of fog lights is approximately 100 meters. When visibility drops below 100 meters, fog lights must be turned on, and drivers should reduce their speed accordingly.
I've been driving for over 20 years, often traveling in mountainous and coastal areas, where fog lights have been real lifesavers. In bad weather conditions, like thick fog or heavy rain, the light from regular headlights reflects back, making it impossible to keep your eyes open and see the road clearly. But fog lights are positioned low and emit a pale yellow light that cuts through the fog without reflecting, allowing me to clearly see road markings, potholes, and pedestrians. For example, last winter when I traveled north, I encountered dense fog on the highway—without fog lights, it would have been impossible to move. They also increase the visibility of your car, reducing the risk of rear-end collisions. However, it's important to use them correctly: only turn them on when visibility is poor, as using them unnecessarily can bother other drivers. Maintenance is simple: just wipe the lens when washing your car and check the bulbs periodically to ensure they're not burnt out. This small tool may seem inconspicuous, but it can keep you safe in critical moments.
