2012 W204 LED Taillight Retrofit DIY
Also, the turn signal on these lights are orange, compared to the red signals on North American W204s. Who knows if the 2012 W204s will have orange or red for the U.S., but I have zero preference either way. But the orange provides a better contrast when signalling so I'll take it.
The new taillights are noticeably brighter than the old ones. The illumination on the back of my garage door was obvious when comparing side by side, even though as of now the rear fogs are illuminated as well. Even with the fogs programmed to be off, these are brighter taillights.
Comparison shot:

Here are the part numbers if anyone is interested:

Installation was fairly simple. You need to remove the plastic cover just above the rear bumper when you open the trunk so that you can in turn move the trunk liner a bit. There are two push pins and a tie hold down on both sides that need to be removed from the trunk liner so you can peel it back just enough to get your hand behind it to remove one of the nuts holding the taillights in place. The other 3 nuts you can access easily enough by removing the covers.

As you can somewhat tell from this picture, without being programmed, the rear fog lights are illuminated. There is a single LED near the top corner, and 4 LEDs above the top light strip. I am not 100% positive if the 4 LEDs above the light strip are indeed the fogs or simply part of the normal illumination. But these LEDs are found on both LEFT and RIGHT taillights. Other than that, the lights work flawlessly and the wiring harness plugs right in, with no error codes displayed on the dash.
There is a shop local to me that does have the developer software to program these lights which I will eventually take to him, the only problem is the language is in German and the translations aren't always direct so it may take some time to find the right menu, etc. BUT, I think they look great even as they are now and would not be upset if for some reason I could not get them programmed to turn off the rear fogs.

So there you have it! All in all I'm very happy with the new tails. It gives the car a fresh modern look, and I love the LED strips. Next on the list is the 2012 front bumper and LEDs, which I'm told might be available sometime in May, although I'm not holding my breath on that.

I checked ebay.de and I don't see any current auctions for the taillights right now. Expect to pay 400 euro + shipping at current market price. I believe www.mbenznl.nl can get the taillights also for 400 euro shipped.
Also, I see no reason why these taillights wouldn't work on ALL W204s.
obsidian05e55, I think your best bet would be to ask around the indy benz shops, ask if they have the STAR developer software I think its called. The truth of the matter is, I'm not sure if my local shop can program them yet either, although he feels somewhat confident he can figure it out.

Another question is, are the new 2012 tailights LED when you brake, or is just those "strips" that stay lit?
The actual brake lights use two incandescent bulbs behind the bottom LED light bar/strip. The only other incandescent bulb is for the reverse light.
