In the event of a normal electrical power failure, specific components are designed to activate automatically to enhance safety and visibility for passengers and crew during an emergency situation. Overhead emergency lights, aisle escape lights, and exterior lights (EXT lights) are all integral parts of the aircraft's safety systems aimed at guiding individuals safely in case of an evacuation or power loss.

Landing lights, however, are not considered a critical safety feature that activates during an electrical failure. Their primary function is to assist with visibility during takeoff and landing phases, and they are not connected to the emergency power system. Therefore, they do not automatically activate in response to power loss, making them the correct answer as the component that does not activate. This aligns with the overall design principles of aircraft systems, prioritizing essential safety functions over non-critical operational features.
