Hoen LED License Plate Lights - very cool!
 

Check out this new release from Hoen on our Q5. The design includes 5W resistors so there's no bulb out warnings. For reference, one pic shows my 2007 RS7 with (noticeably dark!) factory tungsten filament plate lights on the right. At first I thought they might be too bright,. But one day later, I love them!

Do they fit the RS4? For some reason I dont think I'd want a brighter light illuminating my plate... ;)

I was told they are currently hand assembled so availability will be slow for a few weeks until production begins.

Guys don't buy them for the rs; I bought them from hoen and was told no error codes but when I installed them I got error codes sucks because they did look sweet

Same for me. they seem to work if you do not turn on your headlights when you start the car but I leave my headlights on auto and they go on in the garage momentarily - and hence I get a code
