Siemens 52AEE3 Indicator Lamp LED 120V AC Green

Siemens 52AEE3 Green LED indicator lamp is a compact replacement for BA9s‑based indicator and pilot‑light assemblies in Siemens equipment. This LED lamp uses a miniature bayonet BA9s base in the T‑3 1/4 form factor and is rated for 120V, compatible with both AC and DC supplies. The green LED provides a visible status signal suitable for control panels, pushbuttons, and machine interfaces, offering a modern, energy‑efficient alternative to incandescent indicators. As an official Siemens accessory, the 52AEE3 is described specifically as a green LED lamp for 120V operation with BA9s base mounting, designed to drop into standard sockets found in Siemens 52‑series indicators and related panels. Typical applications include signaling run, ready, or on‑state conditions in industrial automation, process control, and equipment enclosures where a clearly discernible green indicator is required. When selecting a replacement, ensure your setup uses a BA9s base and a 120V LED indicator compatible with Siemens indicators; the 52AEE3 is listed by distributors as a green LED lamp for 120V operation with BA9s mounting, aligning with common retrofit scenarios in Siemens control solutions.
