That sounds a bit too long - in 2002 LEDs were just starting to be used in brake lights etc., but not in headlights. Of course, it depends what they mean by "nearly two decades" (I imagine it has to be at least 15 years?) and by "has been around" (in the lab? in prototypes? or in actual cars that you could buy?).
- Huh1337 4y agoWhat about bixenons? Or does adaptive lightning mean strictly LED?
- rob74 4y ago"Bixenon" means just that xenon lamps don't have extra bulbs for high beam and low beam, but regulate the beam via a mask. AFAIK the kind of adaptive lighting that dims only some sectors of the beam to avoid blinding oncoming drivers, pedestrians etc. can only be done with LEDs.
- cromka 4y ago> by "has been around" (in the lab? in prototypes? or in actual cars that you could buy?). Well, since they explicitly mention regions, in that context they rather mean the cars one can buy.
- kalleboo 4y agoWikipedia has citations for a system from 2010 that is mechanically controlled ("movable shadow masks shifted inside the headlamp") rather than using LEDs. Nothing from 2003 though
