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
