In fast-paced operations, clear signaling can help workers make safe decisions more quickly. This LED light system wires into an overhead door controller to change color based on the behavior of the door: solid red when closed, flashing red when in motion, flashing amber just before closing and solid green when fully open. It includes four 5' LED strips to mount on the sides of a doorframe, both inside and outside. For areas with low light or high noise, these signals can make a big difference in worker awareness. Compatible with the most common door manufacturers. Industrial-grade LED strip is designed for tough environments. Five track types are available; see the Description tab below for more information.
