What does a green REV indication above the N1 RPM readout indicate?

Explanation:
The green REV indicator above the N1 RPM readout shows thrust reverser status. When it is lit in green, it means the thrust reverser is deployed and producing reverse thrust, typically used after touchdown to help slow the aircraft. The green color indicates normal, active operation of the reverser. Other indicators would govern ignition or automatic restow functions, but they are not represented by this REV signal.
