Got the new "turn signal lever switch" in the mail and installed it today. Headlights are Now Working! 😀

"Hanky" Easy on the exclamation marks lol..
I was right anyhow. My experience with american cars earlier years (90's back atleast) are that the headlight switch is a open circuit meaning that it runs in conjunction with other electrical harnesses or accessories, meaning again if something else is bad (usually turn signal switch) the headlights wont work
I'm so glad it's fixed and not another project/headache.
