ABSTRACT:
A pointer receives light from a light source and reflects it out of the pointer tip providing a brightly lit pointer suitable for miniaturization and HUD image sources. The pointer has a first reflective surface for directing light from a source into a longitudinal portion of the pointer, and a second reflective surface, parallel to the first surface, for non-dispersively reflecting light out of a tip of the pointer.
