Fog Light

Fog lights are additional lamps for poor visibility; front fog lights light the road low and wide, the rear fog light makes the car visible from behind.

What is Fog Light?

Front fog lights are optional; a rear fog light is required in many regions. They should be used only when visibility is seriously reduced. Some cars use the fog lights as cornering lights.

How it works

Front fog lights use a wide, flat beam below the fog; the rear fog light is a very bright red lamp.

Why it matters for your car

Using the rear fog light in clear weather dazzles drivers behind and may be an offence. Misaligned front fog lights can dazzle oncoming traffic.
