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. Three industrial-grade LED strips included: two to mount on the sides of the doorframe on the inside, and one to mount outside. 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.
