Abstract
An instrument with an illumination ring that edge-lights an opaque dial face with increased light flow by augmenting the conductivity of both the light receiving portion of the ring and a bevel for deflecting light laterally across the face. The increased light flow is accomplished by an extended annular wall portion spaced from the edge of the dial face.
