NKK's LB, YB, and KB series are LED indicators with laser-etched legends. They feature an array of legends including ON, OFF, UP, DOWN, LEFT, RIGHT, or universal power symbol laser-etched on the inside of the indicator cap.
These products use built-in LED light diffusion and a filtering system to produce bright, full-surface illumination with front panel relamping.
