An aircraft emergency exit door indication system may comprise a first plurality of light sources, a controller, and a first sensor associated with a first exit door. The first sensor feedback signal indicates an availability for egress through the first exit door. The first plurality of light sources is operated by the controller based upon the first sensor feedback signal. The light sources may be lights that already exist in an aircraft such as ceiling wash lights, sidewall wash lights, floor path lights, dome lights, or passenger service unit lights. The system may include a second plurality of light sources logically separated from the first plurality of light sources based upon its location relative to the first exit door and a second exit door.
