Of course, many cars have the 7" round, the dual small round, and the rectangle sealled beam lites. It's amazing how we survived back in the early days of bulb headlights then dim sealed beams. Of course we paid more attention to the dark unlined non-street lit highways back then. No cell phones or GPS's to distract us. Just one hand on the Knecker-knob and one on a pretty little knee while cruising the speed limit. Cars and girls weren't ugly back then. The Aztecs still lived in the deep dark jungles.
Do you still remember those tee-vee commercials for promoting telephonebook use, Sir? You know. The ones which went, "Let your fingers do the walking". It would show female fingers walking across a yellow page. When I brought my Renault Le Car to Europe, oncoming drivers would flash their highbeams at me. Once I converted them over to halogen types, I had no negative incidents anymore, after that.
