Abstract
A self-luminous safety sign with variable legend capability. A housing supports a faceplate having safety warnings or symbols thereon. Self-luminous lights, adapted to illuminate selected characters or symbols on the faceplate without external electrical connections, are selectively mounted in the housing. The lights are removable from and displaceable within the housing so that the desired characters or symbols on the faceplate can be illuminated.
