Allen-Bradley 800E-N157B Pushbutton LED Light

The Allen-Bradley 800E-N157B is a blue LED indicator lamp designed as a direct replacement for Allen-Bradley 800E pushbutton assemblies, delivering bright blue illumination when wired to a 24 V AC or DC supply. This part, also cataloged as 800EN157B, is a compact, lightweight LED lamp (about 0.02 kg) rated for 24 VAC/DC and described as full-voltage illumination for the 800E family. It is a discontinued item by the manufacturer as of 2006, so current availability is generally in surplus or third-party replacement channels. Typical applications include status indication on control panels and pilot lighting for Allen-Bradley 800E pushbutton installations in industrial automation where blue indication is required. When installed as a direct replacement, it preserves the original electrical footprint of the indicator module, enabling straightforward retrofits without wiring changes. To ensure LED reliability, operate within the specified 24 V AC/DC range and observe proper polarity during installation.
