Hey, I'm new to the site glad one exists for sure. I have a 2008 Z4 and my wife recently bumped into it with our Nissan Armada breaking the clear shield over the headlight assembly. The Z has the xenon headlights and I have been unable to find anyone who makes and sells the clear shield only. Xenon headlight assembly to say the least isn't cheap. So expensive in fact I am considering replacing both with halogen fixtures. I can replace both assemblies with halogen type for half the price of a new xenon type. I need to know for sure if the lens can't be bought as a separate item; if not and I replace with halogen do I have to change any part of the wiring harness? Some good advice will be greatly appreciated. Thanks in advance.
