A system and method for providing emergency egress path indication by providing a path direction indicator that is hidden from view during normal operation and is exposed to view upon activation by an emergency signal. Upon being exposed to view the indicator may be lighted and may provide light to people seeking exit from the building. In one embodiment the indicator may include a laser pointer further indicating the direction of egress. Visible and Braille text may also be included on the face of the indicator. The indicator device may be located near floor level for better visibility in smoke environments. In the non-visible state, the indicator may present a rugged face to withstand accidental kicks and bumps as may be encountered when mounted near the floor. The indicator may be operated repetitively and nondestructively to allow inclusion of the indicator in fire and other emergency drills.
