i don't want to burst any bubbles; but this isn't likely going to work. longtran or ksfrogman (can't remember) tried taking one of these apart and removing the amber reflector, and it wasn't pretty, or easy. i don't think it ever went back together properly- and if you figure, these things are over a grand US each to replace (xenon, adaptive, at least); that's a lot of money to gamble with.
i would love to hear that it worked, and would be one of the first to line up to get the horrid looking amber reflectors removed, but i think the way they're designed, they were not meant to be opened.
having said that, good luck and keep us posted
