What does a front fog lamp do?

A front fog light is responsible for illuminating the road in front of your vehicle when driving in poor visibility. According to UK and European law a car must have at least one (working) rear fog light, to warn traffic of your presence when they are closing in on you from behind in poor conditions.

Some more modern cars are also equipped with front fog lights, either as standard or as an optional extra, which help you to see the road ahead more clearly in thick fog.

Both these fog lights are important safety features so should be regularly checked and properly maintained.
