RGB LED

Three glowing squares with tiny wires attached to them.
RGB LEDs consist of three LEDs, one of each colour, in a single package.

This photograph was taken with some extension tubes attached to my camera's lens, which turns it into a macro lens, allowing photos to be taken at extremely close distances. With a small current of only a few µA through the LEDs, they glow dimly enough to take a clear picture of the dice and bond wires.
