Abstract
A sign assembly such as an exit sign can be mounted on either a wall or a ceiling of a structure. The sign assembly includes a housing with a frame that supports a square lens. The frame has one wall section that is removable to enable the lens to be removed and reinserted in a different orientation relative to the frame. As a result, the lens can be oriented properly when the sign housing is turned to be mounted on either the wall or the ceiling. The lens is free of electrical contacts and electrical terminals.
