LED traffic signals

Oh yes, I'd say the majority are still incandescent.  While most new ones are LED, many municipalities are in no hurry to change out their existing ones.

Perhaps it's just the areas I've been to have adopted LED's more than other areas. For what it's worth the state I've driven in most is PA.

Are there any incandescent traffic lights remaining in the US? All the ones I've seen are LED.

Plenty.  They are mostly on local (county, municipal) roads and streets, but there are still a fair number on state maintained highways.

Depends on the municipality. Examples from the Vegas area:

City of Las Vegas was very aggressive in changing to LEDs (first reds, then the greens and yellows as that technology developed) in the early 2000s--they were pursing the electricity savings. I'd venture to say that Las Vegas has few (if any) incandescents left in the city.

City of North Las Vegas was probably the first to start implementing all LEDs in new signal installations. However, they have not been very aggressive in retrofitting existing signals, and still has quite a few incandescents, especially in older areas of the city.

Clark County (controlling much of the unincorporated urban Vegas area) and City of Henderson were in between.  They specified LEDs at new installations, but were slower to start replacements, but I'd guess they are both over 80% LED by now.


It's also interesting to note that in many places where there had been incandescent bulbs, the colored lenses were often left in place. It was kinda difficult to tell if a signal had switched--the telltale sign being that green indication usually lost its bluish tint once the LEDs were installed.

Oklahoma City still has a lot of them, especially in the more lower-middle and lower-class areas. The suburbs have a lot more LEDs.

Here most lights are still incandescent. In fact my city recently installed new signals that used incandescent bulbs after the existing ones were torn apart in the November Nor'easter.

It's hard for me to say which is more prevalent around here, though Franklin, TN surprised me by using incandescent bulbs on several new signals.

Maybe the city, literally, thinks it has money to burn as it's the county seat of Williamson County which is one of 20 richest counties in the country.

P.S. I live in Maury (pronounced Murry) County about two or three miles south of the Williamson County line.  (property taxes are much less then in Williamson County)

Wait, Tennessee has traffic signals that have flaming cash as the lighting element? Can you get pictures?

LEDs are "burning out" probably because the circuits they're built on are badly designed or installed.
