An electrical lighting fixture of the "EXIT" sign type formed of a high-impact-strength, molded, substantially rigid plastics material including a transparent principal panel for viewing therethrough a flexible, translucent, light-diffusing sheet imprinted with an informative legend thereon. A perimetric, framing, marginal edge zone of the legend-carrying sheet is coated with a uniformly applied adhesive composition of even thickness. The latter constitutes means for firmly and securely bonding the sheet to the coextensive supporting panel of the fixture. The framing border of the panel, in registry with the adhesive-coated margin of the imprinted sheet, is preferably etched visually to shield the adhesive composition from view. A peelable, protective cover film overlies and is bonded, temporarily, to the legend carrying sheet for removal prior to fastening of the sheet in place on the panel.
