      Lots of places in the US have things like this. It’s different everywhere.

      I think there’s some places still using IR strobes that flash a certain pattern to change a light green. Often they’re only used on main roads or really busy intersections.

        Ours are still the IR strobe variety. Our state use the Opticom system. There’s a little white light and a receiver over each traffic light. When it detects an emergency vehicle, all the lights turn red and the direction the emergency vehicle is going turns green. Simultaneously, all the white lights blink except on the light that turns green — it stays solid to let people know the approaching vehicle is behind them.
