Abstract
An indicating instrument, such as for an instrument cluster, may employ a dial with numerous lighted indicia and numerous lighted graduations, to individually demark the indicia. The indicia and graduations may be viewable on a first side of the dial, while on a second side of the dial, a frustum of a rectangular pyramid may be located immediately behind, relative to a viewer, each graduation. A light emitting diode may provide light into and through the protruding frustum, and a reflector case mounted to the dial may direct light from the light emitting diode into the frustum. Light directed into the frustum may pass through the frustum, through the graduation, and out of the graduation to the first side of the dial. Instead of a frustum, a recessed portion with four sloping and converging sides into the dial may be utilized to produce an illuminated graduation with a three-dimensional appearance.
