Abstract
A holographic center high mounted stop light (CHMSL) employing a linear lamp source comprising a long and narrow cylindrical gas discharge bulb, a non-imaging light concentrator cavity, a plastic light guide and a hologram. The CHMSL is characterized by previously unattainable compactness, weight savings, rear occupant headroom, driver rearward visibility, and electrical efficiency.
