Allen-Bradley 800MR-PT16 Push-To-Test Pilot Light

The Allen-Bradley 800MR-PT16 is a 22.5 mm round, transformer-equipped push-to-test pilot light designed for panel mounting in industrial automation. It operates on 120 VAC at 50/60 Hz and uses stab terminals for fast, secure wiring, with no lens included in the standard unit. Available in red, green, and amber variants (800MR-PT16R, 800MR-PT16G, 800MR-PT16A), this model combines a built-in transformer with a pilot light to provide a reliable status indication inside control panels. Its compact 22.5 mm footprint fits standard 22 mm panel openings, making it suitable for both retrofits and new panel designs where a testable indicator is required. The push-to-test feature enables manual illumination to verify wiring and panel functionality without energizing the main control circuit.
