Ron,
Here's a link to an article that I came across about affordable 12 v RV interior lights, and it seemed like a good idea.
http://www.livinlightly.com/affordable-12v-rv-lighting/ - scroll down to Ikea LEDs - Dioder Kit
This winter we bought two kits and installed them on the under deck trim pieces in the cabin area. Very easy job. They give a nice soft light, not what you would expect from LEDs.
Minimal battery draw. I plan on installing more up in the V- berth area.
I emailed some pictures of the installation on to you.
Cheers,
Mike
