"The Week" mag has a satirical column entitled "Only In America".
I would call that one a candidate.

I'm confused by this. Why is this even necessary?
Today, streetlights are controlled by a photocell, automatically.
When it gets dark, the streetlight goes on, when it becomes light, the
streetlight goes off. If it becoms dark early, say due to a bad storm
and cloud cover, the lights will go on. Why would it even be
necessary to manually turn them on and off?
(When I was very young, the streetlights were controlled by a central
timer, and all would go on at the same time. The timer would have to
be periodically adjusted to reflect changing sundown and sunrise
times. But when they replaced the incandescent with mercury vapor
lamps, they put in photocells.)

"Identify themselves" how? Every streetlight has to have some sort of
identifying name in order to identify itself. What kind of naming
convention would you suggest?

The purpose isn't to identify a streetlight so a tech can "adjust" it;
it's to make instantaneous adjustments throughout the day. As Bill's
original post notes it's to "allow workers to turn lights on or off
and to dim them or brighten them as needed."
See the original CNN article here:

***** Moderator's Note *****
If I had to guess, I'd say that you're both right: a GPS transponder
and logic would allow any streetlight within the bounds of a specified
area to respond to an "all on" command for that area.
And, it would also simplify and speed up maintenance: work crews are
prone to manage records badly, so having a stock of "one size fits
all" lights in a truck, which can be put in place and automatically
tracked, would speed up road crew work and assure more accurate
recordkeeping.

As well it will help eliminate any location ambiguity when faults are
reported by ordinary people who may give not quite accurate location
information so the repair crews will know exactly where to go and what
equipment they will be dealing with.
