LED?s ? Lighting our fuel efficient automobile future

A tiny dot on your finger, as minute as a grain of sand. Fortunately, this speck of material uses electrical energy to generate more white light than any conventional light source in the world. An LED is a semiconductor device ?just a square millimeter in size ? which boasts a remarkable physical property. It can convert electrical energy directly into light and is unbeatably efficient when it comes to energy consumption. Today?s xenon and LED headlights are four times more energy efficient than halogen headlights. It is estimated that by 2018, LED technology should be approximately eight times more efficient than a halogen light. In addition, LEDs practically indefinite service life makes for an intriguing reason to use them in automobile design.
