I think Lee is referring to a rear facing = high-intensity red light, also called a fog light in Europe.  Keeps folks from piling = up on your behind if you don't have a Subaru conversion. 
 
Ahem.  A bit of TIC Friday humor.

Subject: Re: rear fog = light

Has anyone put the euro tail light = with a rear fog light in their van?  I was reading the accessories thread = and lots of us have put front foglights in, some have put on a rear fog but I = haven't heard of the fog in the tail light.  I have the factory switch = with the position for it, would be kinda cool to have the light = too.
 
Lee,
you might want to check to see if a = rear fog light is legal in your area first...
