Question on 12V outlets on ceiling lights

[PeteFug]

We bought our first camper.. Rockwood popup... and apparently the ceiling lights have a 12V outlet for fans etc.. but all I see is a small 1/4" hole or so. Nothing like a car cigarette lighter jack.

Is this hole indeed the 12V outlet? And what does the plug look like? Is it simply a 1/4" mono jack similar to what the stereo jacks you would find on high end headphones?

Endless googling and I have found nothing.. no names.. no numbers... or any reference to jacks other than cig lighter jacks.

The outlet you describe is for running lights into the bedroom wings of the pop-up. Most of the ones I've seen clip onto the upper support rod (we always called them "candy canes") for the canvas and end panel. Here's a link to see a sample of what of these light fixtures look like.

Because those sections of the pop-up fold down, it would be impractical to permanently install lights. The constant bending and compression by the canvas from opening and closing it would surely break the wires (and maybe even the fixture itself) over time. Besides, you have to remove the "candy canes" anyway so you would have to unplug the lights too.

The 1/4 inch hole you noted is indeed a "Mono" Phone jack, center tip is posative..good for pluging in a fan as the plugs are live all the time..
