Schneider Electric, the global leader in digital transformation of energy management and automation, has unveiled the new range of Harmony Tower Lights, replacing legacy signalling products with a modular and future-ready portfolio.

The Harmony range represents a completely new line up of Tower Lights, with four core options. The optimum 70mm XVB7 is a modular tower light that comes in premium materials and design. The modular 60mm XV6 and 40mm XV4 offer a cost effective and modern solution, and the fully customisable smart XVTS features new light and audio configurations for advanced signalling.

The new range delivers value across several applications including water wastewater, mining, metals, food & beverage, automotive, healthcare, pharmaceuticals, retail, logistics, and manufacturing. The modular XVB7, XV6 and XV4 help standardise signalling, simplify maintenance and reduce spare parts complexity. For more advanced requirements, the XVTS extends the range with programmable visual and audible signalling and connected options to help teams respond quickly to changing conditions. These solutions will help OEMs, panel builders, distributors, and end users improve safety, minimise downtime in high-throughput systems, and lower warehousing costs.

“Unplanned downtime is a major productivity drain for any sector. According to the 2025 State of Industrial Maintenance Report only 20% of facilities saw downtime costs fall in the last year and 31% saw them rise. Underlying causes of this downtime such as equipment or process malfunctions can be addressed through better real-time visibility. The new Harmony range enables instant, customisable alerts allowing operators and maintenance teams to act in real-time before failures impact production. Ultimately, we want tower lights to make industrial environments more resilient, connected, and efficient, for all members of the supply chain whether it is one line at a time, or entire facilities.”

Key features:

• High-performance LED signalling delivering high visibility with low power consumption with up to 50,000 hours operating life.
• Modular stack design (XVB7, XV6 and XV4). Configure the tower you need and replace individual light or sound modules.
• Visual and audible configurations across the range, including optional buzzer and sound variants for clearer notification.
• Flexible installation and connectivity with multiple mounting and wiring options, including push-in terminals, with IO-Link/USB options on selected models.

Key benefits:

• Reduce unplanned downtime by helping teams identify machine status and abnormal conditions faster, improving response times across assets.
• Support safer working practices through clearer, high-visibility alerts that improve hazard awareness on the plant floor.
• Simplify maintenance and spares (XVB7, XV6, XV4) by swapping modules rather than replacing complete assemblies, reducing inventory complexity.
• Improve operational consistency by standardising signalling across machines and lines to support quicker, more confident decisions.

A new tower light has been introduced at the top of the new range to enhance asset monitoring and safety. The Harmony XVTS is a smart programmable unit that extends tower light functionality to provide time-based and volume-level visual indications as well as simple alerts. It offers 9 or 15 individual light segments that can be fully customised within the full RGB spectrum and specific light patterns (steady, blinking, flashing, double and triple flashing and rotating). The XVTS is certified to IP69K rating, the highest level of Ingress Protection (IP) available. This means it is the perfect solution for outdoor or extreme applications and has excellent resistance to shock and vibration.

Trusted for over two decades, Harmony Tower Lights are designed to help OEMs, panel builders, distributors, and end users unlock instant visualisation in a wide range of settings. Fully customisable smart tower lights, that even come with their own software, can fit any mission-critical purpose. Modular solutions deliver ease-of-use and seamless integration and mounting to drive down unplanned downtime in any industrial environment.
