I have interior lights now at least on the driver side when open. Now to get a switch to install in the passenger door frame. Would rather take a few seconds to pull the fuse when I remove the doors than not to have a switch or the lights in the dark when the doors are on.
There is also the option of adding a internal switch when the doors are off.
The Mopar OEM solution is a knob that screws over each switch when the doors are off. My Jeep came with these knobs, and they screwed over the door switch. The after market ones are spring ones, which I got because I lost mine. I don't like them for driving because they can pop off. But, they are great for working on your vehicle when you are stationary with the doors open, which is when I use them.
