LED: Light-Emitting Diode - an electronic lamp device, used for indicator lamps and numeric displays (seven-segment displays). Some cameras (such as the Canon A-1) use seven-segment numeric displays in their viewfinders. Originally, LEDs were all red; a little later, green was available, and then yellow; only quite recently have blue and - very recently, white - LEDs been possible.
