Fog lights are auxiliary lamps mounted on the front of a vehicle to improve visibility in foggy conditions. They emit a wide, low beam of light that helps illuminate the road surface and nearby objects, making it easier for drivers to see and avoid hazards.
Fog lights are particularly important for driving in areas with frequent fog, such as coastal regions or mountainous areas. They can also be useful in other low-visibility conditions, such as heavy rain, snow, or dust storms.
