The fog lights improve visibility in poor visibility conditions. They shine forward. It is different from the rear fog light. It shines bright red toward the rear.
The fog light is used to help the driver see the road ahead in foggy or misty conditions. The rear fog light is used to help the driver see the road behind them in foggy or misty conditions.
The fog light is usually mounted on the front of the vehicle, near the headlights. The rear fog light is usually mounted on the rear of the vehicle, near the taillights.
Both the fog light and the rear fog light must be turned on when visibility is reduced due to fog or mist. The law in most states requires that the fog lights be used when visibility is less than 500 feet (152 meters).
The fog light is a white light that is directed towards the ground in front of the vehicle. The rear fog light is a red light that is directed towards the ground behind the vehicle.
The fog light helps the driver see the road ahead by reducing the glare from the headlights of oncoming vehicles. The rear fog light helps the driver see the road behind by reducing the glare from the taillights of following vehicles.
When driving in foggy or misty conditions, it is important to use your low-beam headlights in addition to your fog lights. This will help you see the road ahead and be seen by other drivers.
When may I switch on the fog lights?
You should switch on the fog lights not only in fog but generally in poor visibility conditions. This means also during the day when it is snowing or raining and on dark narrow or winding country roads in order to better illuminate the edge of the road.

- The rear fog light can be very blinding if you switch it on in good visibility conditions.
