Abstract
Abstract A programmable light display system having a carrying case, a semi-rigid, readily penetrable display board mounted in the carrying case and a quill and light assembly for use therewith. Any suitable map, chart or drawing is mounted on the display board and the quill and light assembly is inserted through both the board and map at a predetermined location. After connection of the quill to a printed circuit board connector the light presents an accurate visual display of events occurring at various locations.
