My goodness. Let's get the cart and horse in the proper order, okay? He is using a flasher that currently doesn't work correctly and he had another one in 1977 that didn't work correctly that he's been using since then. We have no idea what that flasher is, and that's an important variable. Whatever bulbs are in use is another very important variable. My information says in 1939 there were no front end flasher fixtures in use by GM (only rear ones) and if that information is correct, the flasher would have been designed to only flash one bulb at a time. But Rick says he has 2 on each side. Another variable and another question mark. If all you have is variables, no equation can be solved...by anyone.
