Description

Overview

Thermo King Status Light Display gives drivers and technicians a clear remote status indication for trailer refrigeration units that use SR-2, SR-3 or SR-4 controllers. The white plug and mounting bracket suit installations where you need a separate visual status point instead of relying only on the controller location.

Use this part when the existing display has failed, the lens or housing has been damaged, or the plug and bracket no longer hold securely. Because the display sits in the operator’s line of sight, it helps make unit status easier to read during daily checks and fault follow-up.

Features

• LED status light display with white plug and mounting bracket
• Suits Thermo King SR-2, SR-3 and SR-4 controller applications
• Status-only remote display format for straightforward visual indication
• Fits trailer refrigeration service work where the original display needs replacement

Compliance and Safety

Trailer Applications

It fits older SR-2 and later SR-3 and SR-4 control setups, so it works for replacement during electrical repairs, panel refresh work and damaged display change-outs.
