An improved LED communication system that expands Stop & Go coverage to the top of a dock door. These signal lights integrate with professionally installed dock restraint systems, changing from red to green when it is safe to enter a properly secured truck. Sold as a set, one unit for each upper corner of a dock door, they are installed above the door header with the included stand-off pipe. Use with the Linear Light for full-coverage door signaling that reduces the risks of accidents.

The Linear Light can be used inside or outside of a loading dock door. When installed outside, it fits easily between close sitting docks. Combine with the corner set for full-coverage door signaling. 33 bright LEDs switch from red to green via user supplied remote switch.
