I have a question for anyone about the headlights. What purpose do the the halogen lights serve, that are next to the xenon headlamps? I have never seen mine come on. The salesman said they must be dummy lights but I figured he really didn't know what he was talking about, since I asked a couple of other questions and he didn't know the answers. I took the rubber cover off the back of the halogen lamps in the engine compartment and the lights are wired. Are they "backups" in case the xenons malfuncion and don't come on? Thanks for any help.
