Damnit! Quit playing with that! My garage lights keep coming on!
Doorbell transformer
I've seen this thing in my attic for many years, and always wondered what it is. It's mounted to a support brace, and close to the light switch, but not connected to the switch at all. It's got one brown wire going to it, which contains a white wire, and a red wire that connects to a couple of screw terminals. Anyone know?
