Garage Door(s)
Garage Door(s)
So, a house I lived in years ago had a detached four car garage that was located up a hill in the back of the house and the doors faced into an alleyway. From the house you could not tell if the door(s) were open.
I installed a contactor to power a 120v luminaire I installed that I could see through a window that faced the house. I used magnetic door contacts on the garage doors. When either door was opened the light would come on and stay on as long as the door(s) were open.
Not the most creative but my wife at the time thought I was a genius, might be why she is my ex-wife.
