I did my LED for 05. Got clear chrome from zomkspeed, I think. They look gangster I regret a bit. Anywho, the ebay seller said it would work for model 04 & up. It did. However. it has light flickering issues which is hard to notice.
I got 4 capacitors from ebay like 2$ each from ebay with same specs. Capacitors are capacitors, folks. Didn't solder them in yet. I will keep you posted when it is done.

I also had to do LED Tail upgrade on E46 by necessities. They are horrible regulating voltage, they all burn out causing weird inconsistent problem. Kudos for BMW...
