Rear Fog Light
The rear fog light is a bright red lamp that makes the car visible in fog.
What is Rear Fog Light?
It is required in Europe. Use it only in poor visibility. It dazzles drivers behind. In most countries it may only be used when visibility is reduced, often below 50 metres, and must be switched off afterwards. Many cars have only one rear fog light on the driver's side. A warning symbol in the instrument cluster shows when it is on.
How it works
The lamp is much brighter than tail lights.
Why it matters for your car
Switch it off when visibility improves. Laws restrict its use.
