Hey Otaku, I bought a whole bunch of finger led lights last year to hightlight grave stones and other parts of my haunt. I was happy with them until I saw that they didn't last very long. I saw your thread and would like to hook them up to a 9 volt battery. How long would you say they last on the 9 volt? Is it as bright as with the regular battery? I'm not very familar with electronics i know how to set up the dowel and such but i don't know how to connect the 270 ohm resistor. Thanks for taking the time to read this.
