For what it's worth, I'd imagine most cities either already have, or are starting
to use LED traffic lights. We have had LED traffic lights in Pittsburgh, Pennsylvania,
USA for at least a couple years. I might even be willing to bet that most(all?) new
lights installed around here are LED.
I see incandescent traffic lights every once in a while, but rarely. Most everything
I've seen for the past few years is LED.
