I was in Radio Shack yesterday just checking out their LEDs, switches, battery holders and the like and ran across something possibly useful. It's part #276-084 the "Red LED Assembly." It looks like you just drill a 3/16" hole that you push the wiring and lower assembly through the hole and it has a nut that allows you to snug down the LED down tight from below. Then you wire it to your switch and power source (or more elaborate system) and you're in business. Has anyone else used this? It'd only be useful in certain areas but I thought it might be an easy way for folks like me who still has a whole lot to learn about prop building etc, to light up their Range Finder or gauntlet etc...Thoughts?
