with hatchback open, can interior lights be shut off to save battery for tailgating
They should time out eventually.
most cars have a switch at their lights to be able to turn them on with the doors closed, turn on when the doors are open but off when closed, and turn them off when the doors are open, if you don't see anything like that than you probably don't. Best way to be sure though is check your owners manual.
