ABSTRACT:
A solid state illuminator and display means are provided for bi-colored ported water level gauges suitable for use in high pressure steam drums or similar water/steam devices to facilitate making an accurate determination of water level in such a device. The illuminator comprises an array of bi-colored solid state light emitting diodes (LEDs), as the light source, and a precision lens to focus the light provided from the LEDs through a gauge body and onto the view screen.
