CRJ PSU reading lights can be tested by pushing the reading light ______ button on the flight attendant panel.

• A. Test
• B. On
• C. Off
• D. Bright

Answer: (A)

The reading lights have a dedicated diagnostic control on the flight attendant panel. Pressing the Test button initiates a quick check of the lighting circuit, causing the reading lights to illuminate briefly to confirm that the lamp, wiring, and power supply are functioning. This is used for verification and maintenance checks, not for normal operation. The On/Off controls are used to turn the lights on or off during service, while a separate Bright control adjusts intensity. So the Test button is the intended way to verify the system’s operation.
