Re: When did high/low beam headlights appear on Packs?

One of the first optical headlamp lenses, the Corning Conaphore. Selective yellow "Noviol" glass version shown.

A Wikipedia record will get us a bit closer:
"..."Dipping" (low beam) headlamps were introduced in 1915 by the Guide Lamp Company, but the 1917 Cadillac system allowed the light to be dipped with a lever inside the car rather than requiring the driver to stop and get out..."
So between Wikipedia's 1917 and Dave's 1921, in those days when a Packard was embellished with drum headlights the high/low beam came into ... beaming.
