I have an old flashlight that runs on a large 6 volt battery that I haven't used in years. I bought a new battery and these bulbs for it, but it turned out that the lantern's switches and contacts were rusted and couldn't be repaired. darn. So now I'm ordering a new one, which means I now have a spare battery and bulbs to run for the rest of my life. :)
