I was in Walmart today and found a book light in the clearance aisle for $1.50. It has a clip on one end that you would normally attach to a book, but it can attach to your shirt. It has a flexible, wire that can be bent however you need, and at the end it has a very bright LED light that is about the size of a dime. Sadly, the batteries are those round kind that are expensive, but for $1.50 they can be thrown away. I am going back to walmart and I am going to get whatever they have left. Can you tell I am tired of trying to spot the tiny drop of blood on my ds finger in poor light when I do my late night checks?
