There are some streetlamps at the end of Camden Road which consist of a pole
with a horizontal arm on top. The long end of the arm holds the main lamp:
the short end pointing the other way has a faint blue light on it. What's
that about?

Chavved-up streetlights?

They've also been installed along the recently refurbished Edge Lane
arterial road in Liverpool, but these have the blue LED at the top of
the vertical pole.

All the 1L Saxo boys with stick-on tinted windows and tin-can exhausts
must be made up.

A wild guess: maybe it's to do with distinguishing between power off
and the lamp failing?
