A tower light, also known as a signal tower or stack light, is a visual signaling device used to convey status or alert information in industrial and commercial settings. Tower lights are typically vertical structures that consist of multiple light modules stacked on top of each other. Each module can emit light of different colors, allowing for a combination of signals to indicate specific conditions or messages. Tower lights are commonly used in manufacturing facilities, warehouses, parking lots, and other environments where clear visual indication is crucial.
