In this video, we demonstrate the ONN-M4P LED signal tower light in a real CNC machine tool environment. You'll see how its diamond-cut crystal lens provides 360° uniform lighting without blind spots, learn about the multiple working modes including steady, red flash, and full flash with optional buzzer, and understand the universal PNP/NPN wiring compatibility that makes installation straightforward across different control systems. We also showcase how this vertical flat industrial tower light effectively communicates machine status for automated equipment.
