Smashed Euro Lights!

[JCE]

Last night someone put their fist into my Euro lights, smashing the lenses in a fist shaped pattern (complete with 4 circular knuckle marks at the edge of the fist sized cracks!). They were Original Equipment Euro lights from a German MB 124, marked with both Hella and MB part numbers on the back of the lights and the mb logo as well. I have a call in to Fastlane to see if they can get Hella lenses. Is there a difference between Hella aftermarket lenses and the ones supplied at the MB dealerships in Europe? Would there be any advantage in trying to get lenses from MB in Europe as opposed to Hella replacements over here.

Also, it looks like rain got through one of the lenses and onto the reflectors. I assume these are 'silvered' units and difficult to clean. Any tips on cleaning would also be appreciated.

Thanks for any help!
