Abstract
A pointer for a gauge or an instrument cluster assembly is provided. The pointer is formed of a light conducting material. In one form, indicia are disposed about the axis of rotation and/or on a surface, the plurality of indicia configured to be selectively illuminated by the pointer. A second end of the pointer may be configured to be selectively rotated adjacent to each indicium of the plurality of indicia and to illuminate the indicia when the light guide pointer is disposed adjacent to the indicia. The second end may be wider than a first end of the pointer. In some variations, the pointer may have a fan shape, and the indicia may be configured as tick marks defining a bar graph. In some forms, opaque material may be disposed on the pointer, the opaque material defining a plurality of indicia on the pointer.
