P.S.- I have read the very thorough set of posts back in 2016, where Stan, John, and others joined in to explain how to design an alternating flasher system for a 154 Signal. Yet, that is way over the top for me. (And, I'm not sure why it was necessary for the components to convert AC power to DC power.)
I'm just looking for an in-line circuit flasher that will work. :-)
Thanks
