The xenon bulbs are not the same as gas discharge xenon bulbs.
They are filled with xenon gas and are claimed to be 30% brighter than stock halogen bulbs. I fitted them to my mom's car, just for the extra brightness. There is a slight difference when you look at the headlights, one with halogen and the other with xenon, but probably not 30%.
The 'real' xenon bulbs are gas discharge type, ie. they do not have a filament but an arc is created between the two electrodes, thereby providing the illumination.
I am afraid that you are going to have to change the whole ballast system. The $1000 seems a little low, people have quoted something like $2200 on this board but that may have been E39 prices.
: I have a 91 M5 and I am wanting the Xenon headlights. Someone told me you need to change the whole ballast to get the Xenon lighting.. but Pep Boyz or Track will sell Xenon bulbs. What is the difference in changing the whole Ballast?
: Has anyone ever tried these Xenon bulbs? Changing $40 worth of bulbs beats doing $1000 worth of ballast work.
