How do you replace the brake light in a 2007 Audi A4?

I cannot figure out how to take off the brake light cover to do this. Please help! Thank you :)How do you replace the brake light in a 2007 Audi A4?if you have the owners manual, you should be able to find "bulb" in the index. I don't see an actual cover, it looks like the bulb holders are simple quarter turn holders.
