Thousands of Firefighters across the world wear VizLite DT. VizLite DT uses photoluminescent (glow-in-the-dark) technology to increase visibility in dark and low light areas. The glow in the dark properties of VizLite DT are not just for firefighters though. Disaster management teams can also benefit from being seen better in the dark. That is why Viz Reflectives will be participating for the first time at the Disasters Expo Europe. Held at Messe Frankfurt, Germany from the 15th to 16th of May, this is a show dedicated to the area of disaster management.
