A Bug's Life

I bought that kind of keyring attachment, with an LED. I did not attach it to the ring that holds my keys, because of the logistical problems some of you mentioned. I put it on the zipper pull of the jacket I usually wear. I can always find it in the dark. When I let it dangle, it hangs right over a reasonably comfortable place to hold a book, when I'm standing at a bus stop. I can also hold it up to shine on street signs, or unzip my jacket to get a better look at a lock I'm trying to open.
