We are working on replacing all of our interior lighting
with LEDs. We buy LED bulbs that consist of a cluster of LEDs on a base that will plug
into our existing 12 volt light sockets. I had two sockets where the bulbs would not work. The instructions said nothing about polarity, but I know that LEDs are polarity sensitive so I reversed the wiring
on my sockets and they now work.
I thought it was strange that the manufacturer's instructions say nothing about the polarity of the socket. Anyone else see this?
