You can buy the Xenon gas filled bulbs which will work with the projectors but they are completely different to actual Xenon headlights. The real xenon bulbs will only work with a HID setup as the light comes from arcing about 20,000 volts from one electrode to another which is completely different to the filaments of a standard bulb. Would be worth getting a HID kit for the projectors though as you do get very good results, expect to pay about £60/70 for a decent kit on ebay. Nice car by the way!
