<strong>The Sure-Lite is an unrivaled, low cost alternative to maintain communication between truck drivers and loading dock attendants. The red and green LED lights are instantly understood as "Stop" and "Go", providing clear signals to dock attendants inside the building and truck drivers outside the building. Units Consist of a ½” thick, black, stress relieved, sanitized HDP (High Density Polyethylene) panel core with all Non-glare LED lights which have a 30º viewing angle, making them highly visible day or night. Recessed lights on the panel face make the lights virtually indestructible, and the low profile panel design ensures impact resistance. Exterior LED Traffic Lights and Interior LED Traffic Lights sold separately. Caution Warning Signs also available.</strong>
