Abstract
An instrument cluster assembly includes a light source for emitting black light and an instrument cluster display including at least one graphic feature that is illuminable by black light. The invisible black light illuminates only the graphic features when contacted by the black light from the light source without illuminating the surrounding portions of the instrument cluster display. Preferably, the light source includes first and second light sources positioned on opposite sides of the instrument cluster display. The light sources are each a single bulb for emitting ultraviolet light. The light sources are positioned between reflectors and the instrument cluster display such that the reflectors are positioned for redirecting black light initially emitted towards the reflector onto the instrument cluster display. The graphic features are preferably made of a phosphoric material.
