Stack lights, also referred to as tower lights, can be either modular or preassembled light units of different colors arranged to provide machine or process status. Choices of steady-on, flashing, and strobe-light modules are offered. Audible buzzer modules can be incorporated into the light stack to help bring attention to the unit.
