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. 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.
