ABSTRACT:
A gauge with a light transmitting pointer and a light-transmitting dial plate having a surface with indicia for a variable represented by the dial, at least one light source facing a hub of the pointer and positioned rearwardly from the rear surface of the dial plate for illuminating the dial plate. The light-transmitting pointer is mounted for rotational movement about an axis normal to the dial plate. The pointer hub is concentric with the axis, extending through the dial plate and projecting both forwardly and rearwardly from the plate, and an indicator projecting laterally from the hub across a portion of the front surface of the dial plate. The portion of the hub extending rearwardly of the dial plate is shaped to capture light directly from the light source so that light enters the hub and propagates forwardly through the hub, and then laterally from the hub into the indicator to illuminate the indicator.
