During annunciator light check via the GTC, how many lights are seen between master warnings?

• A. 6 lights
• B. 10 lights
• C. 2 lights
• D. 4 lights

Answer: (A)

During the GTC annunciator light test, you’re checking that the individual warning lamps illuminate in the expected pattern. When the test runs, the sequence includes the master warnings, and you then look at the row of annunciator lights between them. The design calls for six individual lights to light up in that section. Seeing six lights confirms the annunciator system in that area is functioning correctly and that the panel’s lamp count matches its intended layout. If the count were different, it would indicate a fault such as a missing lamp or wiring issue, requiring inspection.
