The insurance company will only pay for aftermarket items. The Xenon lights are about $1200 each for OEM, and you will want to have them both replaced or it will look weird having one new and one old. My wife hit a truck with a tow hitch in our Mercedes E a few months ago and insurance wanted me to take it to a quick cheap place that used cheap run of the mill paint and aftermarket pieces. I went to other places for estimates and had an adjuster come to my house. They paid ME out the price for repair (less the deductible) and I took the money and got all the parts form bmwmercedesparts.com for 25% off retail. All parts were original and it all came out to about $150 out of pocket for me :-). I also found a body shop who has state of the art 'clean' rooms for painting bays and uses German paints (solvent based), Glasurit in this case (Ferrari even uses this paint).
