    I wonder if you could use four of the LEDs themselves to form a full bridge rectifier?

      Would still need a capacitor or something or it would flicker at 120Hz (in the US) but that’s not much more cost I would hope.

      Also those 4 would flicker more than the rest of the string.

        Did you read “full bridge rectifier” in his voice, too?

      I just looked it up and I’m fairly certain it wouldn’t work. Every time the output waveform gets too low then the led would turn off, which is what creates the flicker. An led needs a constant current to stay on constantly.
