Abstract:
A gauge assembly defining an interior direction and an exterior direction includes a gauge faceplate having a plurality of indicators and a hub that is substantially opaque. The hub includes a hub reflective portion that generally faces toward the interior direction. The assembly additionally includes a pointer having a first portion adjacent the hub and a second portion spaced away from the hub. The pointer is operable to move relative to the gauge faceplate such that the second portion distinguishes between the plurality of indicators. The pointer is substantially opaque, and the second portion includes a pointer reflective portion that generally faces toward the exterior direction. Moreover, the assembly includes a light source that emits a light generally in the exterior direction. The light reflects from the hub reflective portion generally toward the pointer reflective portion. The light also reflects from the pointer reflective portion generally toward the exterior direction.
