here's what I know about HID (High Intensity Discharge) headlights.....they are really really bright, they don't have filaments, they have xenon in them, uh their really really bright, that's about it, my question is what is the difference between what people refer to as xenons and True HIDs, because from what I here xenons are imitation HIDs and not the real thing, also is there a noticable difference in price, I'm sure their is, just wanted to know if it is justifiable to buy the more expensive True HIDs? and if it is that much better how much more do they cost approx. the brighter the better!
