D3Audi

Now, I know this has been brought up in many different ways and many times before, but I'm gonna bring it up again as LED technology is getting better and better as time goes on.. Today I was in Autozone and I noticed that now they carry LED replacement bulbs for 1156/7506 bulbs, etc.. So, has anyone replaced the rear tail light bulbs on the pre-facelift Q7 with LED bulbs? Or on any Audi model too since it's all the same electronic system.. I've heard even canbus LEDs are picky on Audis.. Anybody have any recommendations on bulbs? I eventually want to do the facelift LED conversion but that's gonna be a bit down the road, but I would still like that bright, instant on effect for the added safety.. Has anybody tried replacing stock bulbs and it worked with no errors? I would like to replace my (4) rear tail light bulbs, and rear turn signals, and maybe the front turn signals too (though I may go with those eBay aftermarket V12 DRL/Amber turn signals)
Is there a company that has LED bulbs that works on Audi's or will I need load resistors?
