This LED light kit ties directly into a powered overhead door controller to change the light 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 only when fully open. It includes four 10' LED strips to mount on the sides of a doorframe, both inside and outside. The bright, visible signal makes this system a good solution for improving safety in high-noise applications or areas without a lot of overhead light. Compatible with the most common door manufacturers and programmable to tailor the light timing and colors. Five track types are available; see the Description tab below for more information.
