What is the function of a car's fog lights?

[MacHarmony]

The fog lights of a car serve to alert vehicles in front and behind and prevent accidents. In weather conditions with low visibility, they allow vehicles or pedestrians to notice the car early to prevent accidents. Situations for using fog lights: 1. Heavy rain where the driver's visibility is blurred, making it difficult to judge the surroundings; 2. Foggy weather; 3. When driving at night with no streetlights or poor lighting; 4. Encountering low visibility conditions such as fog, rain, snow, dust, or hail. The fog lights are located on the left rear or left side of the steering wheel. Types of fog lights: 1. Button-operated fog lights; 2. Turn signal lever knob-type fog lights; 3. Center console knob-type fog lights.
