DD has a touch lamp in her bedroom with the lowest wattage globe we could find. Our house is really dark (even during the day!) but the hallway light shines right through the crack where the door hinges to the wall..so this was really our only option. I find the night lights aren't really bright enough.. But they are safe to be left on, just make sure there is nothing near them that can get hot (not that a night light should get too warm anyway)
