Red #276-068 Green #276-069 They need a resistor in series. Switching between day/night brightness is = accomplished by shorting out one of two resistors in series. After the = dimming resistor, the circuit actually splits into four parallel paths, = one for each LED + second resistor. I don't recall the values I used = (have already promised to check when I get a chance), but I would start = with 1k ohm and work up and down until the brightness level looks good.
