Had headlights, then high beam only, now nothing

Okay, we didn't get flooded out, though some of the highways around here, got closed, which nearly cut us off from being able to go anywhere. But, anyway, I still have the headlight issue. I have done various things, in an attempt to figure out what happened. BUT, I am going to start all over again & document each step, as to what I did & what I found. So, starting tomorrow, I will go after it again.
