Does anyone know how to go about putting an aftermarket (Xenon blue or white) light into the sealed housing? I've bought the bulbs, but since the bulb inside the housing is welded in, I can't go about getting the new one to replace the old. Any suggestions? Also, if anyone knows a catalog/company that sells unsealed housings, or sealed housings/bulbs other than halogen (Once again, Xenon blue or white), could they drop me a line? Thanks.
