I have a A5, and I want to change the dome, map and courtesy lights bulbs to LED. Don know how to take out the original bulbs. Any instructions on how to do it?

 

Noramlly a flat head screwdriver and the proper amount of force will allow the lens to pop off. Not to sure on the a5 but my a4 is like that. Changed to leds. Very nice and subtle upgrade.

 

Same as Pa4ul said, but look for a little tab on one side of the cover or another. this will be the side you want to pry on, otherwise you could brake the piece on the inside making it a bitch to put back on. Also, audi is really inconsistent with the size of the bulbs they use, like under one drivers seat will be one size festoon, the other side will be a complete different size. do your research in advance to save yourself some money.
