It's a european thing.

 

I use it when people get on my a$$ on the highway they think you are hitting your brakes and they back off

 

LOL! thats cool. I never noticed that on new audis what year did they start doing it? Maybe thats a dumbass question but o well.

 

i know my 96 has it.. And I Believe the new B7's have it.. so it should be on all A4's

 

Most european cars have one only with reversing light in opposite lens.

 

That works like a charm

 

lol yea its a bright light man i think brigther then the break light at night look at it, it feels like looking at ur head lights i was pretty impressed and i think audi is the only car that has rear fog lights am i correct?

 

no bimmer and benz have it too

 

yea he's right. all the european cars have them. i think thats just becuase its a lot more foggy there than here lol

 

Haha thats true.. I was in scottland about 5 months ago.. and there is a lot of fog there every morning!!!!!
