Title: Good Retrofit Product but not dependable.
Review: This is a great idea. It was easy to attach to my Craftsman miter saw with the factory bolt. I had to open it up and bend the centrifugal switch contact to make it more sensitive. This is right next to the battery so it was easy. Note, it is not bright enough to be used outdoors.9/29/2012: This product died a couple of years ago. Good idea, but not very dependable.
