This idea is rather unique. The idea came to me while watching one of those commercials for the “push-lights” where the old lady finds her way in the dark. Well as corny/weird as this sounds, I came up with the idea of taking little pieces of luminescent tape (the type that is used in photography dark rooms) and placing them on the hinges of our doors and on the toilet bowl. Works great! No need to turn on the lights in the middle of the night. Placement on the door can be anywhere: (where the latch is, or hinges). No more walking into walls or feeling for things in the dark. By the way, I did take B&W and Color photography in high school.
