Allen-Bradley 855E-24GL8 Flashing LED Indicator

Allen-Bradley 855E-24GL8 is a 50 mm control-tower stack-light lamp module that provides a yellow flashing LED indicator for socket-mount installation on compatible 855E bases. It operates on 24V AC/DC full voltage and is the yellow LED lamp option (color code 8) in the 855E family, designed to be paired with other color modules to create a multi-color status indicator on a single 50 mm stack. The lamp is a flashing LED module with a socket-mount LED, enabling rapid visual signaling for on/off states, warnings, or process transitions on automated equipment. Typical applications include manufacturing lines, packaging, and conveyors where clear, immediate visibility of machine status is essential. As part of Rockwell Automation’s Control Tower Stack Lights, the 855E-24GL8 integrates with the base assemblies to form a compact indicator suitable for control panels and machine neighborhoods. This 24V AC/DC module is used in industrial automation environments that require visible signaling from a small, modular indicator lamp, allowing technicians to configure stack towers to match the specific footprint and color-coding conventions of their control system.
