Vintage Cars: sealed beam headlights, sealed beam headlights, ford models

Question
When did Ford first incorporate sealed beam headlights on the Ford models?

Answer
I do apologize for the delay in answering this, but I thought I answered it last week, and since then I've had problems with logging in to this site.  Regardless, the first Fords to have sealed-beam headlights was the 1940 model year.  All cars were required to have them by then.
