Abstract
A wedge for securing in an open position a hinged door having opposite faces and an edge between the faces. The wedge is luminescent and includes a bottom surface, a top surface at an acute angle to the bottom surface, and a pair of opposite side surfaces extending between the top and bottom surfaces. The wedge further includes an indentation on the bottom and each of the side surfaces sized to fully engage the door edge and make substantial contact with the door edge and the opposite faces. The wedge may be used to identify an entrance or exit to a room during no or low-light emergency conditions by using a UV light source to locate the luminescent wedge and location of the open door.
