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

Later on, including the 1935-39 junior cars, Packard (and maybe others) used an interesting three setting headlight beam control until the sealed beam bulbs were made mandatory with the 1940 models.

First, both bulbs burned the low beam filaments (like traditional low beam); second, both bulbs burned the high beam filaments (like traditional high beam); and there was a third mode where the left hand headlight went to low beam while the right hand headlight was on high beam. This third setting provided good light without blinding oncoming traffic.

Two filament bulbs with separate reflectors and lenses were used as was the practice at the time. Bulb filament alignment with the lens was critical to providing correct light pattern.
