Where is the Emergency Lighting System (ELS) located on the B737?

The Emergency Lighting System (ELS) on the Boeing 737 is strategically located near the 2L jumpseat. This placement is critical as it allows the crew to have easy access to the controls and indicators of the ELS during an emergency situation. The proximity to the 2L jumpseat ensures that the crew can quickly activate the system if necessary, enhancing safety for passengers and crew alike.

The emergency lighting system is designed to illuminate exits and critical areas within the cabin in case of an emergency, thereby guiding passengers and crew to safety. Its location is selected to optimize accessibility and functionality in urgent situations, ensuring that emergency protocols can be followed efficiently.
