Emergency lighting during an evacuation should be used as follows?

• A. They illuminate exits and paths to guide passengers to safety, remaining on until evacuation is complete.
• B. They are activated only after the captain approves evacuation.
• C. They should dim to conserve power during evacuation.
• D. They are optional and may be turned off after the first sight of daylight.

Answer: (D)

Emergency lighting is there to guide people to exits during an evacuation, and it must stay on until everyone is safely out. It provides a clearly lit path with exit signs and floor lighting, powered by independent sources so it works even if the main electrical system fails. It isn’t something the captain must approve, and it shouldn’t be dimmed to save power during an evacuation—visibility is essential for quick, safe movement. It’s not optional; turning lights off or relying on daylight could leave passengers disoriented or unable to find exits. Even with daylight, the lighting remains to ensure a consistent, reliable guide through the cabin.
