Night Lights: How Retroreflectivity Works – This 10-minute FHWA-funded video on retroreflectivity dates back to 2001, but its message is still loud and clear. “Night Lights” describes how bright, reflective materials on roadways and traffic safety devices saves lives by improving the roadway for motorists and pedestrians in a variety of scenarios. The video takes the very technical issue of retroreflectivity and defines the process in easy-to-understand terms for those outside of the roadway safety industry.
