I bought a Leviton night light, model 48582-RBO, made in China. I
opened it up and found a single LEd with two wires connected to the
electronics. I'm still scratching my head on how it puts out red, green
and blue colors, rotating thru them slowly. Apparently the LED die has
some active circuitry on it.
Anyway, you should be able to get plenty of light with 4mA or less, and
with both red and green LEDs connected anti-parallel, you should be able
to get it to put out either color with only one pin.
