Allen-Bradley 855T-G10FN8 Flashing Incandescent Light Module

Allen-Bradley 855T-G10FN8 Flashing Incandescent Light Module is a gray-housing, yellow-lensed indicator designed for use with Rockwell Automation’s 855T Control Tower Stack Lights. Operating at 120 V AC, this module delivers a flashing incandescent signal (FN) to attract attention in industrial control panels and signaling towers. The 855T-G10FN8 designation identifies gray housing with a yellow lens and flashing incandescent operation, making it a direct component in a multi-module stack that can be combined with other light or signaling modules within a single base. As part of the 855T signaling family, it is intended for use in applications requiring visible, rapid-flashing status indications—such as process alarms, equipment status updates, and workflow alerts—within manufacturing and automation environments. In typical configurations, this module works alongside up to five light modules in a single stack, enabling customized signaling arrays that convey distinct conditions or alerts across the control system. This part is commonly selected when a bright, fast-flashing yellow indicator is needed to clearly communicate an active alert or caution state in complex machine rows or production lines.
