Help with identifying these lights found in every room in this house (1980). I’m thinking an old security system. One light was lit the other was off. not sure what they are for.
I use to install security systems, mostly honeywell, and I believe you are right about this being an older security system. Every alarm system is a little different but a green light usually means that the system is ready to arm, a red light means it is either not ready to arm or already armed, depending on the system. Sometimes these lights are outside too, to indicate if the house is armed or in alarm. Hopefully that helps.
Good info thanks Terrill & Nicholaus
