An instrument cluster assembly includes an outer gauge that is disposed about an inner gauge. The inner gauge is flood lit and the outer gauge is back lit. A single light guide assembly receives light from a plurality of light source exposed about an outer perimeter of the outer gauge. Light directed through the light guide is emitted through a light emitting edge to illuminate the inner gauge. Light traveling from the light source through the light guide is uniformly transmitted through a curved transition portion to back light the outer gauge assembly.

Flood and back lit instrument cluster

A light guide assembly for illuminating an instrument surface includes a continuous curved transition portion for uniformly directing and transmitting light from a light source to a backlight surface of the instrument surface. The curved shape of the transition portion is tailored to transmit a desired amount of light into the backlight portion and a desired amount outwardly against a back surface of the instrument surface.
