A holographic rear window stoplight for a vehicle having a playback illumination source (115), a prism for optically coupling the playback illumination (PB) into the rear window (113) of a vehicle, and a hologram for diffracting the internally propagated playback illumination (PB) to produce a holographic stoplight image that is visible from behind the vehicle. The playback illumination (PB) can be directed to the prism (529) by acrylic light guides (523,525) and the hologram can comprise a reflection hologram, a transmission hologram, or a rainbow hologram. <IMAGE> |
