Stack lights (aka: signal tower lights, indicator lights, AndOn lights, warning lights, industrial signal lights, tower lights and light towers) are commonly used on equipment in industrial manufacturing and process control environments to provide visual and audible indicators of a machine state or process event to machine operators, technicians, production managers and factory personnel.

Introducing our premium selection of tower lights, the ultimate visual signaling solution that combines innovation and efficiency. Tower lights, also known as signal towers or stack lights, are dynamic devices designed to provide clear and immediate visual cues in various industrial and commercial settings.

Definition: Tower lights are multi-tiered devices consisting of stacked modules, each illuminated by vibrant LED lights of different colors. These modules work in unison to convey important information and alerts, making them indispensable tools for effective communication.


  1. Industrial Automation: Tower lights are a staple in manufacturing and industrial facilities. They indicate machine status, operation phases, and equipment faults, enabling operators to monitor processes from a distance.

  2. Warehouse Management: In logistics and warehousing environments, tower lights guide order fulfillment, convey loading dock availability, and signal inventory replenishment needs, streamlining operations.

  3. Process Control: Tower lights play a pivotal role in process automation by indicating stages of production, material availability, and system readiness, enhancing efficiency and minimizing downtime.

  4. Machine Status: These lights are essential in robotics and CNC machinery setups, displaying robotic arm movement, tool changes, and work cycle completion, allowing real-time status assessment.

  5. Safety Systems: Tower lights enhance workplace safety by signaling hazardous conditions, emergency shutdowns, and fire alarms. They ensure immediate awareness and quick response during critical situations.

  6. Quality Control: In quality assurance processes, tower lights highlight pass or fail stages, guiding operators to execute necessary inspections and maintain production standards.

  7. Energy Management: Tower lights optimize energy efficiency by indicating the need for equipment shutdowns during non-production hours or energy-saving modes, contributing to cost reduction.


  • Enhanced Visibility: Tower lights feature vibrant, high-intensity LEDs that remain visible even in challenging environments, ensuring attention is drawn promptly.
  • Multicolor Signaling: With multiple color options, tower lights offer versatile signaling for different alerts, allowing operators to differentiate between statuses at a glance.
  • Remote Monitoring: These lights enable operators to monitor processes from a distance, minimizing the need for physical presence and expediting decision-making.
  • Reduced Downtime: Quick identification of equipment faults and operational phases leads to faster maintenance responses and reduced downtime.
  • Efficient Communication: Tower lights provide clear and universal signals, transcending language barriers and ensuring consistent communication across diverse teams.
  • Customizable Configurations: Modular designs allow customization of light sequences, colors, and patterns, tailored to specific operational requirements.

Elevate your workplace with tower lights that redefine visual communication. From efficient process control to heightened safety awareness, these lights offer a holistic solution that enhances productivity and responsiveness. Choose clarity, choose efficiency—choose tower lights to illuminate your path towards smarter operations.
