Fog lights are specialized automotive lights designed to illuminate the road immediately in front of a vehicle during foggy, rainy, or snowy conditions. Unlike standard headlights, which shine straight ahead, fog lights are mounted lower and emit a wide, flat beam of light that reduces the amount of light that reflects off the fog, rain, or snow, improving visibility. These lights are typically yellow or white and are used in conjunction with regular headlights. Fog lights help drivers see better in low-visibility situations, enhancing safety on the road. However, they should be used only in appropriate conditions to avoid blinding other drivers.
