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?
