I find LED stop lights very annoying because they flicker.

  That’s also something that could be fixed with a better implementation. (Higher PWM frequency and/or a capacitor to smooth out the PWM signal.)

    Why is PWM necessary at all? Are the power savings of PWM worth the assault on the senses?

      it isn't, it's just easier to generate/control from whatever dumb microcontroller than a current source.

      It's cheaper and easier to implement than "real" voltage regulation.

    Except it wont be fixed because many don't see it as flickers, most don't find it annoying, and the people making the purchasing decision only cares about cost and not quality.

  It's a big problem for the movie industry ;)
