Allen-Bradley 800E-N157R LED Indicator Lamp Assembly

Allen-Bradley 800E-N157R is a red LED replacement lamp for 800E push-button indicators, designed to operate at full voltage from 24 V AC or 24 V DC. This LED lamp fits bayonet-style insert assemblies inside the 800E family, providing bright status illumination when installed in Allen-Bradley control panels. The part is a replacement lamp (not a complete switch) and is specified as 24 VAC/DC with LED illumination, aligning with common industrial automation wiring. Although catalog listings show it as discontinued by the manufacturer (as of 2006), many distributors continue to list new or stock units, underscoring its continued use in legacy installations. Typical applications include panel-mounted indicators on machinery, conveyors, and processing lines where clear red signaling is required and 24 V control circuits are used; it supports standard 24 V systems and offers the longevity of LED lighting compared with incandescent equivalents. When selecting this lamp, confirm your 800E module compatibility and color requirement, as 800E-N157R uniquely identifies a red LED, full-voltage replacement lamp for 24 V systems in the 800E lineup.
