: Do discharge sources (i.e. Xenon) require the projector for light dispersal, or can they be manufactured similar to incandescent bulbs and placed in conventional reflector housings?
You don't need the ellipsoid glass projector lens for HID. Acura, Lexus, MB are some of the marques that come to my mind that have HID without projector headlights.
I guess you're also asking if they make 'retrofit' kits to install in place of normal bulbs? I don't think so - yet. I think some have tried sticking the HID 'bulb' in a normal reflector (hack job) but the light focusing might be off because the 'bulbs' are of different shapes. One other problem is some headlights (dual filament hi/low beam types) can't be retrofitted because there are no 'dual filament' (so to speak) HIDs. Maybe eventually, as mfrs are testing with methods to 'shift' the arc electromagnetically.
