Stack lights from AutomationDirect are modular systems that provide illuminated and audible status indication in all directions. Modular, "no tools assembly" means installation in minutes and adjustments in seconds. Choose from stack light components in either 24V or 120V AC/DC versions including incandescent or LED stack light modules in five colors, xenon strobes, audible alarms, sirens, standard and flashing bases and extension tubes. Choose your color configuration, or order one of our preassembled stack light models for convenience.
