How to Turn on the Rear Fog Lights of a Car?
3 Answers
Method to turn on the rear fog lights: Rotate the light control knob to the "position light" or "low beam" position, then pull the knob outward to the second position. At this time, the rear fog lights of the vehicle will turn on. When the rear fog lights are on, the front fog lights will also turn on simultaneously. Fog lights are lighting signals used in rainy or foggy weather. Their main feature is strong penetration in fog, making vehicles or pedestrians notice them early in low visibility conditions, effectively preventing accidents. Fog lights refer to automotive fog lights, which are installed on the front and rear of the car to illuminate the road and provide safety warnings during rainy or foggy weather, improving visibility for the driver and other traffic participants.
I've been driving for over a decade, and rear fog lights are quite common. There's usually a dedicated button near the steering wheel or on the dashboard, marked with a backward arrow or fog symbol. First, you need to start the engine, turn on the headlights (like low beams), then press that rear fog light button. The key is to use it in low visibility conditions, such as heavy fog or rain/snow, as it enhances rear visibility and reduces the risk of rear-end collisions. But be careful not to misuse it; keeping it on in clear weather can dazzle drivers behind you and may even result in fines in some places. For instance, once I forgot to turn it off on the highway and got flashed by another driver as a reminder—since then, I've been more careful about turning it off promptly. Safety comes first, so it's important to know where the controls are in your car. Always check the manual or consult experienced drivers.
Thinking back to when I first learned to drive, the rear fog light switch really confused me. Now I'm used to starting the engine first, turning the headlight knob to auto or manually switching on the low beams, then locating that fog icon button on the center console – a gentle press illuminates it. This feature is incredibly useful in severe weather conditions, like when driving on national highways shrouded in haze or heavy rain, as it alerts vehicles behind to maintain distance. But don't misuse it for too long; its high brightness can easily affect others' visibility, and occasionally forgetting to turn it off drains the battery. I've also heard that some cities mandate its use only when visibility drops below 50 meters. After years of driving, I've developed a habit: checking the weather before departure and manually activating it when needed. Safe driving isn't just about turning on lights, but also ensuring the system functions properly.
