Why don't you purchase one of the tree stand lights. You place it on the tree, and use a remote control (like for cars) to turn the light on. Put it near your stand, and when you need to turn it on. It will give you something to focus on, and a clear direction. You shouldn't feel so lost or frightened if you know where you are to go.

The first time I steped to close to a grouse in the dark I thought the devil was after me. Now I laugh at the thought.
