Where I lived in the States, they were so that a speeding Police
Cruiser or Fire Engine could signal them on approach to turn green in
Or it could be some remote control, allowing individual shut-off,
instead of block by block.
Or, if you see black helicopters marked 'GCHQ' hanging around, they

There was also a local experiment in the US to provide WiFi for
residents, and they used street light poles to hold the antennae, but
the whole scheme foundered and died. The equipment is probably still
there, if anybody wants it.
Westminster council offer free wireless access in Central London using
wireless access points mounted on lamp post. This is with BT, they use
an SSID of BTWiFi and the service is not that fast (well, it's free).
Now some hospitality buildings I visit also have their guest wireless
provided by BT, and it's the same BTWifi SSID name that's advertised to
use. That one is faster (sometimes upto 20Mbps), but occasionaly I come
across a guest that's unwittedly connected to the lamp post outside the
window, and they are complaining that it's slow. Such fun :-|

Yep, it's like that here. Nearest street light's at least four-five miles
away with a big hill in the way. The nearest small city is 20 miles away,
and contributes no light pollution at all. Friends from London just stand
and stare in amazement.

Without knowing any details, I would not mind betting they form a simple
mesh network - so in the best case, each one only has to reach as far as the
next, or the one after that in the case of single unit failure.
Occasionally one would have a proper uplink.
