They were the rage in the sixties. If it's still working it's obviously reliable, it's been 40 years. My modern smarthome stuff hasn't had that longevity.

There's also new 12 volt lights: cabinet lights, LED tape lights, track lights, exterior landscaping lights. One advantage of 12 volt lights in a house: when there's a power failure, you can just connect it to your car battery!

Great to know! Wow! Thank you.

The house we are buying was built in the 60s, but is made to look like a FrenchChateau . Still, it has never been updated though maintained impeccably. Lots of wallpaper and unusual architecture- weepy mortar, giant metal sliding glass doors & I think we are able to score it because it has the world’s smallest kitchen. Did I mention wallpaper? All 6 baths need updated and de- papered.
