What message is displayed on the Engine/Warning Display when the strobe lights are OFF in flight?

When the strobe lights are OFF during flight, the message "STROBE LT OFF" is displayed on the Engine/Warning Display. This message serves as a straightforward confirmation to the flight crew that the strobe lights, which are typically employed for enhanced visibility and collision avoidance, are not activated at that moment. It's an important status indicator that helps ensure the crew is aware of the current state of the aircraft's lighting systems, especially in situations where visibility is critical.

In contrast, other potential messages could lead to confusion or raise unnecessary alarms regarding system status or operational readiness. The specificity of "STROBE LT OFF" removes any ambiguity, clearly stating that the lights are intentionally not in use, rather than indicating a malfunction or failure in the system. This distinction is important for proper situational awareness in flight operations.
