Quote: The 'Xenon' came to be when HID surfaced and many of the replacement 'bulbs' called themselves 'xexon' to copy the look of the HID.
Ba careful when shopping bulbs. Many say they have 12V 100/90W 6000K color temperature when they are actually colored 55/60 watt bulbs that have the 'color' of a 12V 100/90W 6000K color temperature bulb.
O.k. So in summation
1)Xenon is just a wannabe HID rip off.
2)HID is probably the best but requires a ballast
3)H1/H4 is an upgrade to the factory sealed beams, but not as "good" as HID.
