Rear Fog Lights

December 1, 2009 at 1:35 am 2 comments

Most North American cars have one set of bright lights on the back, of course those are the brake lights.  But some American cars and most European cars have other bright lights on the rear: rear fog lights.Rear fog light on an Audi

If you’re not familiar with this concept, then you probably assumed their lights were malfunctioning or their break lights were “stuck.”

Rear fog lights make it much easier for the vehicle behind you to see your car when fog, rain or snow is heavy.

Some rear fog lights are a pair of lights mounted low on the rear bumper.  Other cars have a single light, mounted near the driver’s side rear turn signal.

There are debates about the validity of rear fog lights.  Some claim they can be confused with brake lights, others agree but believe that is still safer than not seeing the vehicle until it is too late.

Some cars have separate switches for front and rear fogs, other cars have one switch that activates both.

Studies have shown that in North America more people inappropriately use their fog lamps in dry weather than use them properly in poor weather

    Fog lights saved my life. I was driving through the fog on a cold winter day in Spain and all of a sudden I glimpsed a single tiny red light in the fog and slammed on my brakes, just behind a stopped vehicle that had been completely invisible aside from that light. No fog lights would have equalled two vehicles totalled, and maybe lives lost.

    Never could understand why North American vehicles don’t have these, esp. with our snowstorms and multi-vehicle pile-ups
