• Signs are both phosphorescent and reflective. When most glow-in-the-dark signs are not perciptible after 60 minutes, these signs still glow brightly. Keep your warning front and center.

• Signs are screen printed for extra durability onto our special grade of reflective film. This prsimatic or Diamond Grade material is the same material used for top-end street signs and reflective truck stripes.

• Signs are mounted onto 63 mil thick aluminum and have four mounting holes in each corner.
