Signal Towers

Signal towers, also called indicator lights or stack lights, are organised stacks of coloured lights designed to indicate the status of a machine or process. These visual signalling devices come with multi-coloured LEDs or other light segments, each representing different operational states. A signal tower also integrates audible alarms, sounders, sirens, buzzers, and adjustable volumes to enhance its effectiveness. Additionally, these towers provide a clear and easily understandable visual cue for operators and personnel, allowing them to assess the situation and take necessary action quickly.

Why Buy Signal Towers?

Signal towers are a valuable investment that offers several key benefits. These lighting devices improve safety by alerting personnel to potential hazards, increase efficiency by providing immediate feedback on system status, and reduce downtime by enabling faster troubleshooting and problem resolution. They are also cost-effective and come with advanced features, robust construction, and high visibility. 

View Our Range of Best-in-Class Signal Towers:

We offer high-quality signal towers based on lighting technology and signal outputs. Our modern components include sound components, such as a voice annunciator, electronic sounder, and buzzer, ensuring audible and visual indications. Our selection includes:

  • LED Signal Towers – An LED signal tower is an energy-efficient and long-lasting option that provides bright and vibrant illumination. These towers consume minimal power, generate less heat, and give a clear indication of machines or processes.    
  • Blinking Signal Towers – These towers feature a blinking or flashing light pattern to draw attention to critical events or urgent situations. 
  • Flashing Signal Towers – Like blinking towers, a flashing signal tower uses a rapid on-off cycle to indicate a critical alarm or immediate action required. 
  • Continuous Signal Towers – These towers provide a steady, non-blinking light output to indicate a stable or ongoing condition. 
  • Steady Signal Towers – These fixtures provide a constant light output and are used to indicate a stable state or condition.

Typical Uses of Signal Towers:

Signal towers are automation signalling devices that find applications across multiple industries and settings, including:

  • Manufacturing
  • Automation
  • Process Control 
  • Logistics
  • Transportation
  • Emergency Systems
  • Security Systems 
  • Building Management.
