If you can install a conventional outdoor light fixture, you can install a motion sensor light, although aiming and adjusting it takes extra effort.

After months of delay, the Xiaomi Smart Ceiling Light D20 is finally available to buy. Its standout feature is a built-in radar sensor that detects motion to automatically turn the light on or off.

For a limited time, you can find these $40 Aootek Solar Motion Sensor Lights for just $24 at Amazon. These bright LED lights come in a pack of six and can be easily installed in just three easy steps.
