Not sure what brand because I haven't received the tint. I ordered the tint from the guy below, he's on the BMW forums. Honestly it's the best tint I've seen for the rear lights, it's not too dark and looks OEM.

Thanks meme405. I agree, the tails are way too red but the 2013/2014 7 Series now has tinted rears. I'm actually going to have it wrapped professionally because I want it clean as possible and install isn't going to be too much. I might get the little reflectors done as well if I have left over material.
