Who is responsible for activating the Emergency Light Switch on the 737?

The responsibility for activating the Emergency Light Switch on the 737 belongs to the designated flight attendant during an emergency situation. In most configurations, this task is typically assigned to the third flight attendant, often referred to as FA3. This position is specifically trained to handle certain emergency protocols, including the activation of emergency lights to ensure safety and provide visibility in case of cabin evacuation or power failure. The emergency light system is critical for guiding passengers and crew safely to exits, especially in low-light or smoke-filled environments, making it essential that the right personnel are in charge of its operation. In a well-coordinated emergency response, each crew member has specific duties, and FA3’s training prepares them to take appropriate actions when needed.
