Who preflights the emergency lights?

Emergency lighting is a safety-critical system that requires access to the aircraft’s electrical circuits and battery backup to verify everything works properly. Because of that, the formal preflight check for these lights is handled by maintenance. They have the procedures and access to inspect the battery systems, lamps, wiring, and illumination paths behind panels, ensuring the system will function if an actual emergency power source is needed. The flight crew can perform a quick functional check through cockpit indicators or a limited test, but the comprehensive preflight verification, including battery health and path lighting integrity, is outside routine pilot duties and is assigned to maintenance to ensure regulatory standards are met before flight or after maintenance.
