No matter where you are, take just a few seconds to look around you. There's a good chance that right at this very moment you'll be able to spot at least one place (if not several) where light emitting diode (LED) technology is used. Some of the most common applications are as status indicator lights on electronic components, such as computers, televisions and virtually all handheld devices. The bright light produced by LEDs is also used for traffic signals, flashlights, aisle floor markers in airplanes and movie theatres, and for a while, LEDs were even a popular addition to kid's sneakers. Anyway, you get the idea -- LEDs are everywhere.
Of course, automotive applications are plentiful, too. LEDs are used for interior illumination, system status indicators, daytime running lights, fog lamps and perhaps, the most common automotive application to date, brake lamps. So what's missing from this short list? LED headlamps.
