2012 W204 LED Taillight Retrofit DIY
Post pics of the tails on your car... I'm sure they will look better than your tinted tails.

one's with flash and one's without, enjoy!
So, if I understand you correctly, this will allow us to run '12 lights without recoding our SAM?
Also, someone mentioned a difference in the brightness of the brake lights between the two sides. I take it your solution resolved this as well?
NONETHELESS back on topic... the wire that feeds the signal to the fog is the green wire, i believe this is only for US models, if for european as well, then this is referring solely to the driver side tail, no idea what wire you would need to work with on the passenger side)
what i believe the possible issues are that perhaps the resistor i was using [100ohm 10 watt 10% tolerance resistor] may be the first possible problem, the tails led's may need a completely different resistor for the issue, that resistor has worked to give me error free codes on every single area i've added led's (sidemarkers, lic. plate bulbs, interior floor lighting, reverse led's, i got my eyebrow led's pre-resisted from azn so i did not need to toy with resisting them)
for a temporary fix, since i believe that driving around with the fog on looks goofy, i have come to completely cutting the green wire, since i'll have to deal with the error code until another alternative comes out except working w. the SAM i will live with the error code at least by not having the led's on perhaps azn optics can give in some aid being that he's found out our cars response to led's and how to fix the error codes via his resisted bulbs, he may be able to give us some help with the info i have put up, it may just be that i'm using a wrong resistor, any type anyone recommend i should grab from radio shack or even online and give a go incase it gets things working?
guys i really tried getting something here to benefit and help everyone, i assumed that resisting (like a previous member had mentioned here as well) would do the trick, but i'm out of luck, i will keep working on my tails hopefully getting them to work, but until then this is the full feedback i have for everyone, and the route i took! hope this helps everyone for now, if anyone needs any info or help on white reverse led's, sidemarkers, fogs, or floor lighting, i'll be glad to help! until then i will be posting a video in a few for everyone to see mine working without the fog on, and how they look lit up, sorry again guys!

hardware, if there is someone can take a video guide me how to detach tail light by myself, I will be willing to share the research and result I found.
Thanks again!

Any light you can shed on coding the RSAM by DAS developer would be great. I will probably need to visit a dealership to get this coding done so any help you could provide will make it much smoother for me.

body shell and panels on rear in this facelift, so that have to be totally same size in order to fit the original space, that is my understanding.
there are only limited parameter in RSAM. Front SAM is even more complicate. I have confidence but first I need detach my tail light.
the steps will be announced with the name who provides video guidance ;-)

and one... showing you guys the inside of the trunk area which the tails are mounted and removed... it is quite simple it consists of 4 8mm nuts on the back of the tail light inside the trunk, once those are out and you've disconnected the harness and the back light/circuit board that the bulbs are on it pops right out after you push it out from the inside of the trunk outward.
@noodleman, just to verify as well for you they are perfectly smooth without "dimples"
@1lop, i wish he would respond they we wouldn't all be in this dilemma lol
again guys i'll have a video of how it's all one, it is very quick, but i don't want to go dismantaling them out of the car again, but i will give you all just enough information that is handy to do the job on your own without any questions, as for the error fix hopefully master gets it down for all of us and i can connect my fog again

p.s. if you need any help master pm me i'd be glad to give you me number or sn so that i can walk you through any questions you have, glad to be of assistance to all.

I would LOVE to do this mod if we can figure out the coding issues....
