I completed the project you're contemplating a few years ago. The grab handle on my Winnie didn't come lighted but I thought it was a nice touch and wanted to do it.
I bought a lighted, 12v rocker switch from Radio Shack. I installed it on the control panel just to the right of the copilot seat. I tapped in to the 12v from a "lighter socket" housed in the same panel.
I had to remove the grab handle and drill a small hole through the wall in to the coach interior behind the panel with the new rocker switch.
I didn't use the 1156 socket. I'm not sure how I would make that fit inside the grab handle housing. Instead, I bought the OEM light designed to fit inside the handle housing. The one I bought was from a Monaco dealer but I think they're pretty standard size. It cost about $12 as I recall.
It's worked well for three years now... except the lighted feature of the Radio Shack rocker switch quit working.
Best of luck.
