An egress detection system includes an indicator unit having at least three electroluminescent lamps in a linear arrangement and circuitry for sequentially illuminating the electroluminescent lamps on a repeated basis in order from one end of the linear arrangement to the other end of the linear arrangement. The indicator unit includes a plastic extruded panel containing a circuit board on which the electroluminescent lamps are mounted, and a lens covering the electroluminescent lamps and bonded to the panel. The panel includes an electrical connector which allows the panel to be removed from the electronic circuitry and replaced. The electronic circuitry is also provided to sequentially illuminate a group of electroluminescent lamps in one direction in response to a first sensed condition of relative danger and in another direction in response to a second sensed condition of relative danger.

An egress direction indication system comprising: an indicator unit including at least three electroluminescent lamps in a linear arrangement; a first means when activated for sequentially illuminating at spaced intervals to indicate a specific direction said at least three electroluminescent lamps in order from a first end of the linear arrangement to a second end of the linear arrangement; a second means responsive to the illumination of the electroluminescent lamp nearest said second end for extinguishing all said electroluminescent lamps in the linear arrangement simultaneously; and a third means responsive to the extinguishment of all the electroluminescent lamps in the linear arrangement for activating said first means.
