Just one quick question, I just bought a 99.5 A4 and last night was the first time I have drove it in the dark. I noticed that all the lights including the 3rd brake light light up when I turn the lights on, and get brighter when I hit the brakes. Is this normal or did someone possibly install the wrong bulbs? Thanks for any help.

 

All of mine are on when I drive at night, and get brighter when you hit the brakes. Very normal.

 

You are fine mine is the same way...........
