Really like the lighting visibility (and aesthetics) of the B6 rear... Rear of B7 is "so-so" in a more mundane Honda-esque, SAAB-esque way

But thanks for coming into our forum and telling us our cars look like Honda's.

They signal red as far as I know.

I feel it is much easier for the driver behind you to see orange (some call it amber)
My 98 A4 had all red signals in the rear. My 2003 has amber and I can tell when someone is following they see the much brighter amber rear signal. This gets their attention and they back off. I feel very strongly that the amber rear signals are much safer than all red.
