An illuminated sign is comprised of single piece molded plastic front, intermediate and rear frame members which are substantially coextensive with the width of the sign. All of the characters are formed on the intermediate frame member and they fit into a front frame which serves not only as a support but as a means for masking those parts of the intermediate frame which connect between characters, for example, and which should not be illuminated. The sign is hingedly mounted to a fixed support member which, in turn, supports fluorescent tubes which run along the length of the sign for illuminating the characters to make them visible at night as well as during the daytime. The sign swings down on its hinges to its normal readable position wherein it is secured to the support member by means of quarter-turn fasteners which effectuate a seal by compressing a gasket which is interposed between the sign and the supporting structure.
