By the way, what's the situation with lights which are only for a
pedestrian crossing (ie not for a road junction)? I thought that
these always had a flashing amber phase between red and green,
during which it was legal for cars to set off or drive across
providing the crossing was clear of pedestrians. I was surprised the
other day to find a pedestrian-only crossing where the lights went
to solid amber instead of flashing amber.

There are lots like that in Liverpool - all the way along the A59
(Scotland Road and extensions) for example.

Ah. OK. How do the installers decide which type of pedestrian lights to
install and how do road users know which type are being used - apart

Puffins should not have flashing amber, because of the way they are
supposed to work.
