Abstract
An emergency light system which incorporates flashing strobe type of lights located along the aisle(s) of an aircraft, or other passenger carrier, would provide flashing arrows indicating the location of emergency exits. The sequential firing of the flashing lamps will further create the effect of a moving light beam to lead passengers toward the exit area(s). Also, with programmable control means, there can be stroboscopic type flashing lights to direct egress to only those exits which are open.
