I remember the old Vacuum operated wipers on school busses and big trucks..................

I had an old Chevy half ton pickup with vacuum wipers. They still worked but were crotchety.

I think it’s pretty cool that Corvettes had vacuum powered pop-up headlights all the way into the 1970s (IIRC).

I wish I could remember that far back...and I drove a school bus in high school!
