Signal Division 141-120B Blue Flashing Light

The Federal Signal 141-120B incandescent flashing beacon, commonly cataloged as Signal Division 141-120B Blue Flashing Light, is a compact 141-series warning lamp built for industrial signaling needs. It operates on 120 VAC, uses a 1/2-inch NPT pipe mount, and comes in a blue lens housed in a weather-resistant enclosure rated for indoor or outdoor use (NEMA 3R). The unit measures about 5-1/4 inches tall and 5-1/2 inches in diameter, making it a low-profile yet highly visible beacon for equipment status and safety signaling on factory floors, warehouses, and control panels. As a member of the 141 series, this incandescent beacon provides a reliable blue flashing indication where a durable, pipe-mount warning light is required, compatible with standard conduit systems and suitable for hard-wearing industrial environments.
