856T LIGHT MODULE 70MM STEADY LED BLACK HOUSING RED OUTPUT

The ALLEN-BRADLEY 856T-BT4 is a 70 mm stack light module that provides a steady red LED indication for status signaling on machinery and control panels. Designed as a single-circuit light module, it operates on 24V AC/DC and delivers a constant visual signal suited for assembly lines, conveyors, and industrial equipment. The compact 70 mm diameter fits standard stack light towers and the steady LED reduces maintenance compared with incandescent lamps. Ideal for electricians, maintenance technicians, and plant managers replacing or upgrading signal towers, this module installs into existing stacks to clearly indicate stop, fault, or emergency conditions.
