My wife ordered me a box of 40 LED finger lights from Oriental Trading Co for around 7 dollars. They come in red green blue and white mixed. The kids love them after dark, they even put them on the dog collars. Great for black dogs in the dark. I took the white ones to put on my fingers for working on stuff after dark, I was surprised at how well it worked, much better than a flash light. I am going to try them on the bike tonight, I see no reason why they wont work just like the wired in LEDs except they can be moved at will. I don't know how long the batteries will last but none have failed after several hours of use. Not saying this is going to compare with a professional LED installation, but its worth a try.
