History of bracket headlamps

Could someone give me a confident (authoritative) history of Pierce Arrow using bracket or “New York” headlamps?

What I know is that New York legislated that the spacing between headlights could be only such-and-such distance, which necessitated Pierce Arrow to provide bracket lamps after they began the fender-mounted headlamps. Such a law I’ve always found to be rather odd with Pierce Arrow being such a prominent New York-built automobile.

Now, what I don’t know is:

1) Was this New York State as a whole, or just New York City?

2) Why did New York do this when no other state did?

3) When did this legislation begin?

4) How long did it last? ie: When was it legal to put headlights on the fenders in New York?

5) Did Pierce Arrow offer bracket headlamps right through to the end of production in 1938?

You do see quite a few examples of bracket headlamps in the 1920’s, especially on the Models 33 and 36. They aren’t as distinctive as fender lamps, but being big they do look good. They are very imposing and impressive.

Thanks for the history lesson —- Scott
