Will the white PA "IN USE" light illuminate if a PA is being made by a flight attendant?

Explanation:
The white IN USE light is a status indicator that lights whenever the PA microphone is active and transmitting. When a flight attendant uses the cabin PA, the PA system is opened for transmission, so the light illuminates to show the PA is live. It isn’t limited to being in flight or to a specific command—it's simply indicating that the PA is in use. Therefore, the light will illuminate.
