How do they work?
Got a set of Xmas lights. Gawd knows how they do them at the price.
Blue and White. PS/controller gives a variety of programmes. Including flashing the blue and white alternately, or all on together. But only two wires from the PS. I can see reversing the polarity could have one colour or the other, but how both at once with no apparent flicker? Fast switching? -- *The statement below is true.
