Low beam, front position light and sidemarker functions are performed by LEDs; high beam and turn signal functions use filament bulbs. The headlamp is supplied by Koito. Full-LED headlamps supplied by AL-Automotive Lighting were fitted on the 2008 V10 Audi R8 sports car except in North America. The Hella headlamps on the 2009 Cadillac Escalade Platinum became the first U.S. market all-LED headlamps. Present designs, such as those available as optional equipment on the 2010 Toyota Prius, give performance between halogen and HID headlamps,[47] with system power consumption slightly lower than other headlamps, longer lifespans and more flexible design possibilities.[48][49] As LED technology continues to evolve, the performance of LED headlamps is predicted to improve to approach, meet, and perhaps one day surpass that of HID headlamps.[50] [Reply]   [No Email]
