Hello,

I saw this about pelican crossings and the associated crossing
signals.

BTW, I've noticed for a while now that the green on pedestrian
crossing signals no longer flash flash, but rather go dark. Is that
because of the stress that the flashing signal puts on the bulb
filaments, thus meaning more money expended for bulbs, plus the
labour involved in changing them?

All new installations use LEDs so that is a diminishing problem if it exists
at all.
