Norway - At highway 155 in Nes i Hole, 220 radars have been installed
on light poles. They detect oncoming traffic and adjust the strength
of the light. By doing this, the 9 km/5.5 mi stretch saves a whopping
2100 kWh per week. The extra investment will break even after just 4.5
Her indoors has now rung the council 6 times about the failed street
light outside our house. Because of its situation on a corner, the area
is pitch black and the pavement (and the road) is potholed.
She has been told that they only repair lights every 3 months and
hospitals have priority, whatever that means. When asked who would be
responsible if an old person had a fall because of the lack of lighting,
the council representative said she could not answer that.
The appointment of the current contractor featured in Private Eye at the
Worse than this is that small "refuge islands" have been installed in
the centre many of the main roads. These have a central pole with a
light on top and a lit-from-beneath bollard each side. On most of these
all the lights have now failed and many of the bollards have
disappeared, presumably having been hit by vehicles.
They hung Christmas lights on the streetlights through the town, but
only on the working ones. It's hard to understand why they couldn't have
put a box of bulbs on the cherry picker before they set off.
Yes, she has a reference number from them.
The council website reports

Not hard at all its compartmentalisation often occurs due to different bits
of the services being tendered out to different companies.
Wait till you see what happens next month when banking services can be run
by anybody as long as you money stays in a bank its safe. I see BT running
cash machines or doing transfers, and advice for ininvesting in Tescos or
almost anything else, also of course if the banks lose their money making
delayed transfers, they will want to charge us for keeping our money.
As for streetlights, it is very difficult to tell who to complain to. all
lamps are supposed to be numbered and some are done by Higways agency,
while others are council. In london its split three ways, Highways agency,
TFL and each council.
In theory they should all talk to each other but we all know how reliable

The council will not save money due to street lights not working. They are
not individually metered. The Council pay based on the number and type of
lamps and the number of hours of datkness measured by a typical photocell.
Only the Electricity Supplier would get a small benefit.
The council should want to repair it as it is still being charged for the
power it isn't using.

"As a way to curb street lights power consumption and unnecessary
light pollution, Geolux proposes to selectively and progressively turn
on the street lights when they are needed, that is, when a pedestrian
or when traffic are detected on the street."

Sounds good if it works, but I noticed they haven't included costing but just claimed up to 80% saving without saying how much this will cost to install.
We've used zigbees here, but they seem to hgave gone out of fashion now.
Surely it'd be better using AI and IoT for this.
Why you should be worried about connected street lights
but I think this is relevant aspect,
"Retired astronomer Christian Luginbuhl at the Flagstaff Dark Skies
Coalition published a research paper in 2014 which showed that if you
switch from high-pressure sodium to white LED, the 'sky glow' will
increase tremendously - even if you match the total number of lumens
(the brightness thrown out) of light."
Technology to the rescue
It doesn't have to be this way and, as usual, technology does have an
answer. Even progressive Flagstaff needs to take advantage of LED's
undoubted economic benefits, but unlike most towns it's not rushing in
and buying the cheapest LED solution without first trying out night
sky and eye-friendly alternatives already on the market.
The town is currently testing both narrow-band amber (NBA) and
filtered white LED (FLED). NBA fixtures - recommended by the National
Optical Astronomy Observatory - emit mostly yellow light, while FLED
is a normal white LED fixture with a glass filter over the top that
suppresses the shortwave blue light.
Together those technologies largely solve the problem of sky glow,
while also achieving the same low electricity costs, but they're
newer, so don't have economies of scale."
In US recently, in one city: "Officials say about 34 miles of copper
has been stolen from highway lights citywide."
"Copper theft continuing to darken Tulsa highway lights, setting back

"Theres been a recent rash of thefts," Ball said Wednesday. "After we
got the lights back on, they came back and stole all the copper that
