What does a rear fog lamp do?

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.

The Volkswagen Beetle: The ‘people’s car’

A classic of its time, originally named the Volkswagen Type 1, it soon became nicknamed the Beetle due to its unique shape, and subsequently the bug. The unique looking car was designed by Ferdinand Porsche for Adolf Hitler, who wanted a cheap and simple mass-produced car to travel around his country’s new road network.

The new model Beetle, originally launched to celebrate the original classic in 1997, and with an updated successor in 2011, was designed around the VW Jetta platform sharing much of its build with the Jetta and Golf. VW announced in 2018 that the Beetle would finally be removed from production in July 2019.
