Halogen headlights came about when they separated the bulb from the
lens. Sealed Beam headlights were the law for a long time. When I
lived in Canada (80-81) I bought and installed a set of headlights
that had bulbs that you replaced. They were legal in Canada but not
down here. Somehow I just never changed them when I moved
back! :-) (Not corps but feds. It was against the law!!! I think
it is NHTSA that makes the laws what car corps can have on their cars
besides emissions)

That's right, European cars had the much brighter and better
designed headlights for years before the U.S. As I recall, halogen
lights were illegal in this country at that time, essentially
because there were no U.S. manufacturers making them. Eventually
Sylvania, I think, started making them and all of a sudden it was a
good idea, and legal.
A nice little example of corporations holding back something that
would benefit the public because it did not benefit a U.S. corporation.

Any typical tungsten bulb suffers the same problem over it's life,
it's output goes down. The neat advantage of halogen bulbs are
that they do not diminish brightness as they get older. Therefore
all US cars now have (which our European friends had for a long
time) Halogen bulbs.
Remember when Square Headlights came into American cars? It was a
rule change from the Feds that allowed it, even though Europeans
had them for years before we did.
