Stacklights, called signal towers, are modular, stackable devices that provide illuminated and audible status indication for machines, systems, or processes. They are available in a variety of colors; in flashing or permanent incandescent, LED, or Xenon lighting; and with audible alarm options.
Stack Lights
Category Selection
Stack lights (or signal towers) are modular systems that provide illuminated and audible status indications that can be seen and heard from a distance in all directions. Signal towers with a modular design and "no tools assembly" means installation in minutes and adjustments in seconds.
Pre-assembled or custom configurable signal tower models are available in 24V, 120VAC/VDC, or 100-240VAC versions with incandescent or LED modules in a variety of colors and light functions. Additional options include Xenon strobes, audible alarms, sirens, standard or flashing bases, and a selection of mounting styles.
