A light emitting diode (LED) is an electronic component that emits (gives off) light when an electrical current is passed through it. Initially used for digital numerical displays like clocks, watches, and instrument gauges, LEDs are now used in home and commercial lighting, video displays, outdoor billboards and signage, automotive applications, and aviation lighting.
