Yeah, yeah, yeah I'm sure this has been posted at one time or another, however I didn't find the info "I" was looking for when I did a "search". Sooo help a brother out. I want to put a yellow light in my jet pack beacon that runs off a 9V batt. or equiv. and I'd like to get the parts from Radio Shack. I went to attempt this and was shot down from the sales clerk. Now I know this is possible, I just don't know how to do it, so if any of you Mcguiver's out there that know, please share.
