What does a solid green light next to a system's status indicate?

A solid green light next to a system's status indicates that the system is operational. This visual cue is part of the aircraft's status monitoring system, which provides pilots with immediate, clear information about the functionality of various systems. An illuminated green light confirms that the system is functioning properly and is available for use, contributing to the overall safety and efficiency of flight operations. This visual indication reassures the flight crew that the associated system is ready and performing as expected, which is critical during both normal operations and emergencies.
