The 1000 hour life is of course at rated wattage, which is a fairly rare
event when used as a speaker protector. So almost certainly it did what
it
was supposed to do and protect the tweeter.

Wow... Can you imagine ordinary listenable program material burning out
that
light? The amp must have broken into oscillation or something.

Nope, I can well imagine someone at a party turning it up that far. Happens
all the time, which is why the thing is there in the first place.
But yes, slightly lesser morons would turn it down before the globe actually
blew. Of course if the manufacturers weren't trying to hide their speakers
deficiencies, they would put the globe on display, and call it an overload
light, so the head bangers actually knew it was time to turn it down. That
would of course rely on the user interpreting the difference between a
slight glow and full brilliance, something the manufacturers don't think the
users can manage. Besides some manufacturers rely on income from repairs,
rather than a reputation for not needing them.

A faulty amp is a possibility of course, but less likely in this case IMO.
The far more common amp problem for speakers is a blown output stage putting
DC on the speakers, which of course is a problem for the woofers, not
tweeters.
