  • Patent number: 9990868
    Abstract: A compact exit sign includes a main body having an open frontal portion, an annular side wall portion and a rear panel portion including a central opening extending across greater than half of the rear panel, and a front plate including a face portion provided with exit indicia. The exit sign can be selectively converted between single and double face exit signs by snap-connecting a first, solid and non-transparent insert to the main body across the central opening of the rear panel to establish a single face exit sign and snap-connecting a second, exit indicia containing insert to the main body across the central opening of the rear panel to establish a double face exit sign. A lighting system is housed within the main body for illuminating the exit indicia for either of the single or double face configurations.
