Reverse lights(2 part question)
Has anyone successfully changed out the awfully dim stock bulbs to brighter LEDs without getting the bulb out warning? Also, what size (921, 725, bayonet, etc) are OEM reverse light bulbs on a 2011 Q7?? (search yielded only 1 thread with minimal info)
Thanks in advance,
Brian

Thanks for bringing this up as upgrading the reverse lights has been something I've thought about too. Interested to see what works and what improvement can be gained from an led upgrade.

Finally got around to replacing the reverse bulbs on the 3.6, as that is the one that is parked outside and typically gets backed down the driveway (garage has the 4.2 and a project car). I used 921 bulbs rated at 50W (5W x 10) with 50W, 6 ohm resistors.
Biggest pain was getting the resistor wiring tucked in the bumper so the light housing would seat back all the way. This junction must be in just the right spot and even at that it must be smaller and you need something to help shove everything back and out of the way. I used a hack saw blade to do the wire pushing.
Bulbs are definitely brighter, but the rear hatch glass is dark enough that the only benefit I've noticed from the driver seat is from the side mirrors.
All components were purchased on Amazon and are Prime.

Looking at upgrading mine to LEDs here after christmas, looks like we can get around cutting the harness for the resistor if you're willing to spend a little extra.
I'll be using:
LEDS
Inline resistors

As a follow up question, I would be curious if anyone has successfully installed any aftermarket LED bulb setups that do not flicker on cold diagnostic testing. I would love to do conversion for fog lights, DRL, etc. but if that means that all of my lights will flicker constantly when not in use I do not want to do it.

I haven't gotten around to it yet, nor ordered the parts. I have a few LED reverse lights from DeAutoKey, I bought a few years ago for my Touaregs' reverse lights.. They were the wrong ones, but I kept them figuring I would probably use them later. Enter today, I temp installed one last week before a trip to Orlando, hoping they would function even if that involves a 'Bulb Out warning' popping up. Well the light barely lit up, and I didn't want to waste time installing the other side to find the exact same result. So here I am, sitting at work, reviewing the options forward. Reading more about the resistor I posted up, I'm going to elect to use something else. I usually pick up bulbs from Retrofit source, so I've skimmed their site and found a set of resistors they offer, that have a better housing and supposedly lower thermal output. So that's where I'm at, going to order these and wait and see!
