I just changed my left headlight bulb and I noticed the whole (reflector) assembly is loose. I took it to the dealer and they said it needed to be changed, and that they they have to order the parts. Since I imagine that will cost a bundle, I am thinking, why not see if the lights can be converted to xenons (or bi-xenons). Wife has a Lexus with bi-xenons and there is a big improvement with night visibility. So, does anybody know a good third-party bi-xenons for this model? Or, are the 2005 S80 xenons installable on this model year?
