About OEM LED Headlights
Headlamps
Automotive headlamp applications using light-emitting
diodes (LEDs) have been undergoing very active development
since 2004.
The first series-production LED headlamps were factory-installed
on the Lexus LS 600h / LS 600h L presented in 2007 for 2008
models. 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.
Designs as of MY2010, such as those available as optional
equipment on the 2010 Toyota Prius, give performance between
halogen and HID headlamps,with system power consumption
slightly lower than other headlamps, longer lifespans and
more flexible design possibilities. 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.
LEDs are increasingly being adopted for signal functions
such as parking lamps, brake lamps and turn signals as well
as daytime running lamps, as in those applications they
offer significant advantages over filament bulbs with fewer
engineering challenges than headlamps pose.
