Abstract

A vehicle instrument cluster for indicating a value of a vehicle parameter. The vehicle instrument cluster includes a display member formed of a transparent material and display segments integrally formed within the display member. The display segments are configured to diffuse light and the display segments form at least a portion of indicia associated with the vehicle parameter. A first illumination system has a light source and a motor connected to an optical member. The optical member is movable in response to a change in the value of the vehicle parameter. The optical member selectively directs the light from the light source to within the display member to illuminate at least a portion of the display segments that form the indicia to indicate the value of the vehicle parameter.
