Hero999, You've been so kind to work on my project, even to provide a potential solution schematic. As mentioned above, I have no electronics background and it is apparent to me that the IR-switched solution I was envisioning is beyond my abilities. In my ignorance, I don't understand what your schematic is doing - much less am able to put the pieces together. I googled the two parts listed to find out what they are; however, it's still "Greek to me". I think if I were set on pursuing this project I would need someone to develop a turn-key solution that I could connect to a power source and signal LED. I imaging that would be cost prohibitive for such a trivial project. Now, if I were developing a solution to mass production, that would be another story. Again, thanks for all your effort.
