What are the functions of front and rear fog lights?

Here are the functions of front and rear fog lights:1. Front fog lights are used to improve road illumination in fog, snow, rain, or dusty conditions.2. Rear fog lights are used in heavy fog conditions to make the vehicle more visible when viewed from behind. Here is some related information about front and rear fog lights:1. The purpose of front fog lights is not illumination, but to provide a high-intensity scattered light source that serves to alert oncoming drivers. If used under normal conditions, they can be bright enough to dazzle the eyes of oncoming drivers.2. Rear fog lights are red signal lights installed at the rear of the vehicle, with higher luminous intensity than tail lights, to make the vehicle more easily detectable by other road users in low visibility conditions such as fog, snow, rain, or dust.
I used to drive long distances frequently, and the front fog lights were particularly useful when driving in fog or heavy rain. They are installed at a low position on the front of the car, with the light shining directly onto the ground. This helps penetrate the fog or rain curtain, reduces glare from oncoming vehicles, and allows you to see the road clearly. The rear fog light acts like a striking red marker, alerting vehicles behind to maintain a safe distance in poor visibility and preventing rear-end collisions. That time when I encountered thick fog in the mountains, the headlights weren’t effective, but as soon as I turned on the front fog lights, the road became visible. The rear fog light ensured safety. However, be careful not to misuse them—using them in good weather can impair others’ vision and drain the battery. Remember, fog lights are primarily for severe weather conditions. Keep them turned off under normal circumstances to save energy, and during maintenance, check whether the bulbs and wiring are aging. This way, they’ll be reliable when you need them most.
