Where are emergency exit lights typically located on an aircraft?

Emergency exit lights are typically located at every door and escape hatch on an aircraft to ensure that passengers can find their way to the exits during an emergency situation. These lights are critical for visibility in low-light conditions, such as during a power failure or when smoke obscures the view.

Strategically placing lights at every exit ensures that all potential evacuation routes are marked, providing clear guidance that can help both crew and passengers navigate safely and efficiently to the nearest exit. This comprehensive approach enhances the overall safety and preparedness of the aircraft, making it possible for everyone to evacuate swiftly in an emergency.

Other options, while they may highlight certain areas of the aircraft, do not provide the same level of safety and accessibility as having emergency exit lights at every door and escape hatch, which is essential for effective evacuation procedures in critical situations.
