Headlight Tech - BETTER TO LIGHT A SINGLE CANDLE THAN TO CURSE THE DARKNESS

摘要

I'm willing to bet that drivers only think about headlights during one of two events: when for some reason they can't see at night, or when an oncoming car blinds them. Like the alternator, these critical pieces are overlooked-until they don't work. And that's a shame, because for the gearhead, there's a lot of interesting tech behind the glass. Like, for example, did you know that an HID headlight is like a lightning bolt in that a glowing arc of electricity illuminates the fixture? Plus, automakers are calling on headlights to increase not only safety but also fuel efficiency.
