PERMALIGHT® photoluminescent safety signs glow in the dark and thereby remain visible to observers for an extended period of time during a blackout, underneath a heavy smoke layer or simply at night. Often signs are printed onto white plastic. Should the power fail, those signs are not visible in the dark. PERMALIGHT safety signs light up in the dark and show their message. Choose from easy peel-and-stick adhesive film or rigid PVC signage. Choose from standard stock signs or have us custom-make a sign with the language, graphic, text, colors of your choice.
