A concealed light fixture sign includes a flange having stencil openings formed therein that define a message. A container extends from a rear surface of the flange and provides light through the stencil openings. The container is configured to be installed completely within a recess behind a mounting surface with the flange positioned substantially flush with the mounting surface. Translucent inserts positioned within the stencil openings are removable to provide access to an interior of the container after installation of the light fixture sign.
