Alot of work goes into designing proper optics for HID's, simply dropping in a rebased xenon bulb and wiring up ballasts doesn't get you there.
As far as the actual lights go, xenon lights are better. They are brighter, last longer and use less power than halogen.
As stated though, a correct projector is needed to make the brighter light really
effective. Without a projector the xenon glares and reflects light all over the place and blinds on-comming traffic.
