Have an now old fashioned Surefire Executive Elite 2e question . Kept it on a living end table so if the lights went out. Not an EDC anymore. So trying it out, it was dead. Put in new batteries and there was a bright flash and then nothing. I think the bulb blew. Given the old tech, doesn't seem worth buying a new bulb or some conversion head as we have a whole new set of LED flashlights. Thoughts?
