Shop modular and pre-assembled stack lights from QLIGHT and TEND in red, amber, green, blue and white, running on 24V AC/DC or 110-220VAC with IP65-rated protection for industrial and automation environments.
N.A.W. Controls’ Stack Lights range (also known as signal towers) covers modular and pre-assembled solutions from trusted brands including QLIGHT and TEND, for clear visual and acoustic signalling in industrial, manufacturing and automation environments. Available in red, amber, green, blue and white, they make it easy to communicate machine status, process conditions and alerts at a glance.
With voltage options covering 24V AC/DC and 110-220VAC and durable IP65-rated protection, these stack lights are built for reliable operation in demanding industrial settings. Choose from individual LED modules, poles, mounting brackets, buzzer units, flashing modules and complete assemblies to configure a solution that suits your machinery, production line or control system.
Stack lights, also known as signal towers, provide clear visual or audible indications of machine status, production flow, warnings or operator guidance. Each colour in the stack communicates a different condition, helping teams respond quickly to faults, stoppages or normal operation.
Stack lights come in 24V AC/DC for low-voltage equipment and 110-220VAC for mains-powered installations, giving flexibility for both modern automation setups and traditional industrial machinery. Always check compatibility with your equipment’s power requirements first.
Yes. Many modules and assemblies feature a strong IP65 rating, protecting against dust and low-pressure water exposure, suiting factories, processing plants, workshops and semi-outdoor environments. Buzzer-equipped models may feature IP54, still solid protection for most indoor use.
Can I build a custom stack light configuration?
Yes. The range includes modular LED light segments, poles of different lengths, brackets and top covers, so you can select the colours, order and height you need – from a simple one-colour module to a multi-layer stack with a buzzer.
What’s the difference between pole-mount and direct-mount stack lights?
Pole-mount stack lights raise the signal higher for better visibility across a wide area, ideal for busy factory floors. Direct-mount units attach directly to machinery or panels for a compact, stable setup. Both support flashing or buzzer options.
