Abstract

A sign (10') includes a sign housing (16') defining an internal cavity (32'). The sign housing (16') includes front and rear faces (18', 20') having indicia or an instruction thereon, and includes flashing lights (58) above and below the indicia. A recessed flange (86) defines an opening in the faces (18, 20), and a lens (87) is secured over the opening and to the flange (86) so that it is flush or planar with the faces (18', 20'). Light elements (28') are positioned within the sign housing (16') behind the lens (87). The sign housing (16') is sealed to protect the light element (28').
