Most green lights in the US have a blue tint so that color blind people can see the blue. Most but not all, which is really frustrating as a colorblind person. More than once I've been sitting at a light until my wife told me it was green as there is one light near me without that blue tint. (we are making a left turn so light has both the round red stop light and the green left turn arrow on at the same time)

There is no clicking/hum that distinguishes those 2 states? If that's the case, you should probably check with council to have those nearby lights changed into disability-friendly setup. You may be surprised how effective it may be, maybe council has some part of the budget allocated to this so they will give it higher priority (or not, but at least try, you can help other people too)
Crosswalk lights in the US may have audio but usually not the roadway lights, and depending on the jurisdiction the crosswalk may not always get the light at the same time as the roadway, not to mention that you may not hear it if you are at the centermost lane of a road four or five lanes wide in each direction.
There is for pedestrians, but when I'm in my car with the windows closed I can't hear them.
I'm pretty sure the international agreement on road signaling completely forbids any stop and go light from being on the same place, so that you can distinguish them without depending on any color.

But well, the US never follows any agreement it signs, so yeah, that happens.

Sure, but green is so washed out for me that the green position may not be there at all for all the good it goes. If you tell me the green is lit I'll look close and see it is on, but I will not notice without being told to look.
