What is this? I found it under the eve on the front of a house

It’s a photocell light sensor used to turn lights on after dark and off when it’s light out.


Thank you. I wasn’t sure there doesn’t seem to be any outside lights.

On when dark and off when light electric light sensor.

That little clip above the sensor slides over the sensor thus making lights come on with less darkness outside.


Good to know, Mark!..Thanks!
