Signal / Dock Guide Lights

The Tri Lite Stop-Go Loading Dock Safety Light is a safety signaling device that can help alert truck drivers and loading dock personnel to the status of docked or docking trucks. They can also be used as signal lights in a variety of applications including parking lots and lift gates, inspection lanes, access to secured areas or buildings, car washes, drive-up windows, and as a starting signal for water slides or motor raceways. Stop-Go Loading Dock Safety Lights are available with standard incandescent lamps or long-lasting LEDs.

Tri Lite's new LED Loading Dock Guide Light Set helps provide added safety at loading docks by improving a truck driver’s depth perception when backing into an open dock. They provide an ideal reference point for drivers to align a truck trailer with the warehouse door while backing into a loading dock.

When used together, Tri Lite's Stop-Go and LED Guide Light set provide a simple and reliable safety system that reduces the risks of accidents in and around the loading dock.

Stop-Go Loading Dock Safety Light Set (SG30)

Stop-Go Loading Dock Safety Light Set (SG30)

The Stop-Go Loading Dock Safety Light Set greatly increases worker safety and is the best visual communication package for most loading docks. The set consists of two light units, the SG10 and SG20 for the inside and outside of the dock. A six-foot communication cable connects the two units. The set operates with a toggle switch that controls the inside and outside lights. The SG30 can be ordered without the toggle switch (indicated by "NS" in the part number) for installations utilizing a remote switch. Remote switches can be obtained from an electrical contractor or installation professional; they are not offered by Tri Lite.

How the Stop-Go Loading Dock Safety Light Set Works

When a truck is parked securely in the loading dock, the inside light is turned green. This indicates to the forklift driver that it is safe to enter the trailer. When the green light is on inside the building, the outside light is red, indicating that the truck should not move. Once the truck is unloaded, the inside light is turned to red. This tells the forklift driver to stay away from the truck. Simultaneously, the outside light is turned green, indicating it is now safe for the truck to pull away.

Stop-Go Loading Dock Safety Light with Switch and Flasher (SG20)

Stop-Go Loading Dock Safety Light with Switch and Flasher (SG20)

The Stop-Go Loading Dock Safety Light with Switch and Flasher (SG20) consists of a housing and two lamps designed for use beside the loading dock door on the inside of the building. Three leads exit the back of the light; a common shared by both lights, a hot for the red lamp and a hot for the green lamp (115 VAC also have a ground.) It includes a three way toggle switch on the bottom of the housing. Flip the switch one way and the green light comes on; flip it the other way and the red light illuminates. The center position turns the light off. The SG20 also has a flasher built into the unit. Electrical installation consists of two power leads (plus a ground for 115 VAC.)

The SG20 is also available without a toggle switch (indicated by "NS" in the part number) for installations utilizing a remote switch for automation of the light. When installed this way, the light can be set to automatically change colors after a door is opened. Remote switches can be obtained from an electrical contractor or installation professional; they are not offered by Tri Lite.
