motion sensor light

Detects then illuminates

A motion sensor light is a light fixture that turns on automatically when it detects movement nearby, typically through infrared sensors that register body heat or motion within a certain range.

Common for outdoor security lighting, driveways, and entryways: The motion sensor light clicked on as I walked up the path.

They conserve energy by illuminating only when needed.
