Guys, I just found out today while at my BMW Zentrum that there is a third choice.
Stock the LCI's are clear. And the Blacklines are dark black. But there is something called "sport" which is a light smoked color LCI tail. That is what I ordered for my 135i. I throw up some pics next week when I have the lights on my car.
PS: IF you look up on RealOEM for a German model 135i LCI you will see the Sport tails lists with Xenons and AHL options.
