Pipe/Surface-Mount Stack Lights

These lights have lenses that snap in and out, so you can easily swap colors or change their position in the stack. They meet NEMA 4X for protection from corrosion and washdowns.

Use the extension pipe and mounting flange to make the light taller (both sold separately).

Use the vertical-mount bracket (sold separately) to mount the light to a vertical surface such as a wall.

Build-Your-Own Stack Lights

Design a stack light with your choice of light pattern and color. Start with a base, then add up to five modules total—twist and lock them together. All components except for replacement bulbs meet NEMA 4X for protection from corrosion and washdowns.

Sound module must be placed in the top position.

LED bulbs last longer than incandescent bulbs and provide years of maintenance-free operation.

Select-a-Color Stack Lights

Choose from seven colors, including nontraditional colors such as magenta and turquoise, for a custom four-light stack light. Assign colors by pushing your machine's wire leads into the spring-clamp terminals in the light's base. As your operations change, update the colors by opening the base and rearranging the wire connections. Lights have LED bulbs for years of maintenance-free operation. They have clear lenses, which are helpful in bright environments where it can be difficult to see whether a light is on or off. They meet IP66 for protection from high-pressure washdowns.

Electronic-Alert Stack Lights with Buzzer

Get notified about equipment issues even when you aren't around your machines. These lights connect to your computer via Ethernet, allowing you to set up email alerts when there is a problem with a machine, server, or conveyor. The buzzer can emit both continuous and pulse tones—pulse tones alternate on/off to draw greater attention than continuous tones. Lights have an LED bulb for years of maintenance-free operation.
