Cyflect Exit Sign with Adhesive Backing, 8a ^2x10a ^2 - Glows and Reflects Enable safer evacuations in the dark. Patented Cyflect is the only product where 100% of the surface area both glows and reflects. Cyflect products are non-toxic and waterproof. The intense green glow or white reflection of the exit sign is visible through fog and smoke, and unlike glass-bead material, will reflect equally wet or dry and from oblique angles. With an industrial adhesive backing, installation is easy - simply peel and stick.
