Abstract

A system to selectively display a symbol at a location on a vehicle window. The system includes an arrangement of a fluorescent material at the location, wherein the fluorescent material: a) is sufficiently transparent in the absence of ultraviolet (UV) light, b) fluoresces when illuminated with UV light, c) and has a shape corresponding to the symbol, and a UV light source configured to illuminate the location with UV light to display the symbol. Such a system may use unfocused UV light sources to illuminate the symbol shaped fluorescent material as opposed to focused UV light sources such as UV lasers.
