Allen-Bradley 800L-18L10B Indicator Light Module

Allen-Bradley 800L-18L10B is an 18 mm blue LED indicator light module in Rockwell Automation's 800L series, engineered for panel mounting on commercial-grade and light-industrial equipment. Built with a plastic housing and a blue LED lens, it is specified for 120 V AC input at 50/60 Hz, with the 800L family also offering a 120/240 V AC configuration for strobe illumination where required. The compact 18 mm diameter fits standard indicator holes on control panels, making it ideal for status signalling on machines, conveyors, and packaging lines, where operators benefit from quick visual cues. As part of the 800L indicator lights lineup, it complements other 800L devices and signaling components to deliver clear, durable status indications in demanding environments. The blue LED provides high visibility in a variety of lighting conditions, and the 800L ecosystem supports use with matching housings and lenses to maintain a uniform appearance across a control station. Typical applications include signaling machine readiness, fault indication, process status, and operator alerts in manufacturing lines.
