Crud, so the whole inside of your VX is completely dark with just the back door open. Now I know why you guys want some lights back there haha.

If you wanted any kind of lights to turn on automatically when the door is opened, you would have to install some kind of push sensor on the rear door to activate and deactivate them. I know it sounds complicated but it's probably easier than you think. I'll do some research and see if I can find some nice switches, and maybe put together a cargo light kit for you guys that turns on/off when the door is opened and closed.
