What is the indication of a properly functioning LED flashlight?

A properly functioning LED flashlight is indicated by being present and secured with a green light. The green light signifies that the flashlight is in good working condition and ready for use in an emergency situation. This color is universally recognized within safety protocols to denote that equipment is operational and safe to use. The other colors suggest potential issues or different states of operation, which would not meet the standard for a properly functioning emergency light source. Thus, a green indicator is critical for ensuring that flight attendants can quickly and effectively manage emergencies.
