Rayolite

Sometime in the late 1960’s, Rayolite (then “I.T.L.”) was given the task by the Department of Transportation (DOT) to improve highway visibility during foggy, dark and rainy conditions. Their solution at the time was a cubed corner reflective lens that could be installed on highway lines for delineation during night-time. This lead to the creation of Raised Pavement Markers. Now, with the technology and innovation Rayolite is capable of along with the goal of safer highways, they manufacture and sell high quality RPM’s throughout the U.S. & 20 more countries worldwide.
