Claim:
An instrument face plate assembly comprising: a face plate having an obverse face and a reverse face with indicia in the form of a numerical progression on the obverse face; a light transmitting band disposed above said indicia, said band being divided into a plurality of bounded areas, each bounded area being of a different color; a rotatable shaft extending through said face plate; a pointer disposed in front of said face plate adjacent to the obverse face, one end of said pointer being affixed to said shaft such that the pointer is rotatable with the shaft; and a light member disposed in back of said face plate adjacent to said reverse face and substantially behind and parallel to said pointer, one end of the light member being affixed to said shaft such that the light member is rotatable with the shaft and the pointer, and said light member being capable of illuminating one colored bounded area of the band at any given time; whereby, as the shaft is rotated the pointer indicates a particular indicia and the colored bounded area above that indicia is illuminated from behind causing colored light to be visible both peripherally and directly by an observer, said colored light being associated with the particular indicia indicated by the pointer.
