Final answer:
The escape slide lights come on during an evacuation when the slide is deployed and ready for use.
Step-by-step explanation:
During an evacuation, the escape slide lights would typically come on when the slide is deployed and ready for use. These lights are designed to illuminate the path of the slide, making it easier for people to see and navigate the slide in low light conditions.
For example, in an aircraft evacuation, the escape slide lights would activate when the slide is deployed from the emergency exit, allowing passengers to safely evacuate the aircraft.
Some escape slide lights may also have additional features, such as high visibility color or reflective strips, to enhance visibility and aid in locating the exit slide.
