An illuminated address sign ( 20 ) including a housing ( 22 ), a lens ( 24 ) positioned in the housing, an at least semi-transparent, flame-retardant barrier ( 26 ) positioned in the housing adjacent the lens, and an electroluminescent light source ( 28 ) positioned in the housing adjacent the barrier. Housing ( 22 ) includes a front surface ( 30 ) having an opening ( 32 ), first and second side surfaces, ( 34 ) and ( 36 ), respectively, top and bottom surfaces, ( 38 ) and ( 40 ), respectively, and an open internal cavity ( 42 ) opposite the front surface. Lens ( 24 ) includes a display side ( 52 ) and an internal side ( 54 ) with side ( 52 ) being visible through opening ( 32 ) and side ( 54 ) positioned in cavity ( 42 ). Barrier ( 26 ) includes a front side ( 56 ) and a back side ( 58 ) and is positioned in cavity ( 42 ) with side ( 56 ) in contact with side ( 54 ) of lens ( 24 ) and side ( 58 ) positioned in cavity ( 42 ). Light source ( 28 ) is positioned in cavity ( 42 ) adjacent and/or in contact with side ( 58 ) of barrier ( 26 ). A back plate ( 62 ) is joined to housing ( 22 ) to enclose lens ( 24 ), barrier ( 26 ), and light source ( 28 ) within cavity ( 42 ).
