Front Fog Light Symbol

The front fog light symbol features three downward-slanting lines on the left side of a semicircle with a vertical bar. Fog lights, typically referring to automotive fog lamps, are installed at both the front and rear of vehicles.

Due to reduced visibility in foggy conditions, drivers' sight is significantly impaired. These lights extend the visible range, particularly with yellow anti-fog lights which offer superior light penetration. They enhance visibility for both the driver and other road users, allowing approaching vehicles and pedestrians to detect each other from greater distances.

The primary function of fog lights is to make the vehicle more noticeable to others during adverse weather conditions such as fog or heavy rain where visibility is compromised. Consequently, fog light sources require strong penetrative qualities. Most vehicles utilise halogen fog lights, with LED fog lights representing a more advanced alternative.
