12 volt

First question. Why do my 12 volt lights get brighter when I plug into shore power? Next question is if I tap into my 12 volt reading light in the bedroom can I use those wires to run a pig tail to install a cigarette lighter plug so I can use my c-pap machine that runs on 12 volt?

  • Cpap machine is kind of important. I would run a whole new circuit with a fuse or circuit breaker and 12v accessory plug just for the Cpap machine.
  • If you're still running incans you should replace with LEDs... the kind that will tolerate voltage fluctuations.
  • Your lights get brighter when you plug into shore power because that turns on your converter/charger. Whether you can power your cpap machine depends on the wire size, the fuse size protecting that wire and the amperage of your machine.
