Fog lights are specialized lights on vehicles designed to improve visibility in foggy or misty conditions. They emit a low, wide beam of light that is aimed close to the ground and helps drivers see the road immediately in front of them and the lane markers more clearly in fog, snow, or heavy rain. These lights are typically mounted low on the front bumper or grille of the vehicle and can be turned on independently from the headlights. Fog lights are valuable for enhancing safety by reducing glare and improving visibility in adverse weather conditions.
