The leader in industrial automation and control solutions

Tower stack lights / Signal Towers provide high-visibility visual and audible signaling for clear machine status indication, safety alerts, and efficient industrial communication. Multiple color configurations, flash patterns, and buzzer functions to match specific operational needs. Energy-efficient LED technology delivers superior brightness, long lifespan, and reliable performance in demanding environments. Pre-wired and pre-assembled designs reduce installation time, while a wide range of sizes, mounting options, and technologies make these signal towers ideal for virtually any industrial application, including Andon Station systems for real-time production status and operator notifications.

Tower Stack Lights 5 all colors, red, amber, green, blue, white

Tower stack light with IP protection for dust, splash, washdown, or outdoor use (IP54-IP65)

Environment Protection

Choose the right ingress protection rating (IP54-IP65). Standard industrial environments may only need basic dust and splash protection, while washdown, outdoor, or high-moisture areas require a higher-rated enclosure.

Long-Life LED Modules

Use LED modules for long service life (50,000+ hours), low power use, and better vibration resistance. LEDs are a better fit for modern industrial equipment than older incandescent bulbs that burn out faster and are more fragile.

Audible Alarm

Add a buzzer (85dB), with adjustable volume, when visual signals may not be enough. Audible alarms help alert operators to faults, stoppages, or urgent conditions, especially in busy or noisy production areas.

Modular Stack Design

Build the signal stack around your specific application needs. Modular industrial tower lights allow to combine different colors, light patterns, and alarm options so each status condition is clear and easy to understand.

360° Visibility

Make machine status easy to see from across the floor. Bright LED modules provide clear 360° indication, while pole mounting options help raise (4″ to 40″) the signal above equipment, guards, or other line-of-sight barriers.

Flexible Mounting

Mount the light where operators can see it best. There are several options: use direct mounting for local machine status, wall or side mounting for panels and Andon displays, or pole mounting when the signal needs to be elevated.
