The system, called Matrix LED, was introduced in Germany in mid-November as a 2,400-euro ($3,200) option on the 74,500-euro A8 executive sedan. (The feature hasn’t been approved yet for the U.S.) BMW charges 2,500 euros for an LED lighting package, which can’t create non-blinding gaps for specific vehicles.
LEDs, or light-emitting diodes, have replaced Xenon, which was first introduced by BMW in the 1990s, as the hot, new lighting technology for high-end carmakers
LED technology uses less energy and lasts longer than traditional halogen bulbs, which have been the industry standard for decades.
