I have a 2011 A5 2.0T coupe. I'm guessing the interior light are LED since I have LED taillights and daytime running lights. I have bulb out on my MMI and it looks like it may be one of the dome lights that have the dimming feature when closing the doors. I was thinking of contacting deAutoLED based on their presence on a lot of forums and lifetime guarantee. I guess I have two questions. 1. Do I have LED interior lights? 2. Has anyone dealt with this vendor and are they reliable? It seems on Amazon you can buy LED kits with almost 100 lights for about 12 bucks. Seems cheap and to good to be true. Thanks in advance for any suggestions on replacing interior lights. Who knows, maybe I'll replace everything. They do seem a bit bright in the photos.
