Very interesting. I haven't had that problem either. what year is your tour? there is a recall for the headlight switch. Has that been done? If not, it might be what's causing the instrument lights to not work. Not sure about the backup lights. I have heard that the wires that are covered up w/ that black plastic piece on the hinge part sometimes get knicked or pinched and that might cause the back up lights to not work... just a few thoughts.
