Abstract
A light housing for an instrument panel includes an interior surface for reflecting and blending light from a plurality of light sources substantially uniformly from an opening. The light housing is mounted to a circuit board and surrounds a plurality of light sources. An interior surface of the light housing includes inwardly protruding ribs that reflect and direct light to blend the separate light sources and provide a substantially uniform light intensity for illuminating a rotating pointer.
