Abstract
An emergency lighting apparatus comprises an elongate substrate adapted to pivot and hang from a door knob like a lever and define a handhold in a first end and support a motion sensor and a light array at a second end. The emergency lighting apparatus also includes a motion detecting lighting device comprising the motion sensor and the light array. A method is disclosed for hanging the elongate substrate on the door knob via the handhold for egress lighting and removing the elongate substrate from the door knob for use as a flashlight via the handhold.
