Hello,
I just purchased and installed 2 new light fixtures in our hallway. There is a switch at each end of the hall and 2 lights at each end. Either switch works both of the lights.
The previous light fixtures did not have the ground connected even though the boxes have the wire. The old fixtures (circa 1976) do not even have a ground wire. I went ahead and installed the new fixtures without connecting the grounds, assuming that due to the hook-up it was intentionally not connected. I turned it on and it works.... for now. I would sure sleep a lot better if someone could confirm this sounds like a reasonable set-up.
Thanks, Gary G
