The Tri Lite Stop and Go Light is a safety signaling device that can help alert truck drivers and loading dock personnel to the safety status of docked or docking trucks. Stop & Go Lights are equipped with our new long-lasting LED lamps. Suitable for indoor and outdoor use.
Stop & Go Lights have many diverse applications, including signal lights for parking lots and lift gates, for inspection lanes, for access to secured areas or buildings, for car washes, for drive-up windows, and as starting signals for water slides, motocross racing, etc. The SG20 is a more sophisticated product. It has a three way toggle switch on the bottom. The center setting turns the light off. Flip the switch one way and the green light comes on; flip it the other way and the red light illuminates. In addition, the SG20 has a flasher built into the unit. Electrical installation consists of two power leads (plus a ground for 115VAC). The lights are designed to be hardwired into the power supply.
