From a driver's standpoint, they're the greatest thing since sliced bread. The drivers who have them aren't complaining about them. They light up the road markings much better.... You're driving at night, 'round a bend and � ouch! � you're staring down the barrel of high-caliber headlights boring right at you. Some creep left on the high beams, you grumble. But no, those are too bright, too white, almost blue, like an iceberg. What the heck are those lights? Can that much glare be legal? Isn't it unsafe? The lights are xenon-gas-ignited, high-intensity-discharge (HID) headlights, often known simply (and incorrectly) as xenon (ZEE-non) headlights. They are wildly popular with some motorists, and, if properly aimed, they are quite legal. I too have them on my truck and it's rare that I use the high beam. They would make for a killer back up light as well, but I haven't engineered that one yet.
