Do not leave a light, especially loaded with alkaline cells, in the attic! The summertime heat will usually damage the cells pretty quickly, leading to a leaking cell.
Let's see, 2 cars with 2 each = 4, 2 people with 2 each makes 4 more = 8, two in the kitchen =10, two in the nightstand=12.
Man, you're short of lights already! There are none in the garage, or the tool box(es), or the briefcase, or the camping gear box/crate, or in the closet, or hanging on the wall in the stairway to the basement, etc.
