856T-BT8 Replacement Yellow Light Module for Allen-Bradley 70 mm Stack Lights

856T-BT8 Replacement Yellow Light Module for Allen-Bradley 70 mm Stack Lights

Trying to find the right replacement module for your Allen-Bradley stack light? If your part tag or old module reads 856T-BT8, this is the correct match. It is a steady yellow light module built for the Allen-Bradley 856T Control Tower system, a common style of signal light used on machines and equipment to show status at a glance (running, stopped, needs attention, and so on).

This module powers on 24V AC/DC and simply mounts onto the base that is already on your stack light. It does not come with its own base, so if you do not already have one, you will need to order that separately.

Common Applications

• Replacing a burned-out or damaged light module on a stack light
• Adding a yellow status level to an existing signal tower
• Machine and equipment status indicators in a shop or facility
• Indoor or outdoor signaling where a durable, sealed module is needed

• Simple installation: Mounts directly onto a compatible 856T base, no tools beyond basic hand tools.
• Weather and washdown ready: IP66/67 rating protects against dust and water spray.
• Runs cool and lasts long: LED rated for over 60,000 hours of use.
• Standard voltage: Works on 24V AC or DC power, common in industrial control panels.
