3 wire 2 color led for running / turn

ok here is what i have ......... a 3 wire 2 color led light , the 3 wires are black being -ground , red being white light , yellow being amber light

if you hook the black to ground and red to +12v the white lights turn on  , same with the yellow wire to +12v the amber lights turn on , but you can not have both the red & yellow hooked up to turn both lights on at the same time they cancel out the other.

if you hook up the red being white lights to +12v the whites are on and if you add the yellow wire to +12v the whites turn off and the ambers turn on .

what i am wanting to do is have the amber lights turn on all the time being the parking/running light and use the white lights as the turn signal lights.      from what i can tell both the red and yellow will have to have +12v supplied to them all the time and the yellow wire will need to loose the +12v to allow the yellows to turn off and the whites to turn on.

 i already have the turn signals wired so i have a +12v output from the turn signal flasher and the parking/running lights are wired with a +12v output ............... so can anyone tell me how you would wire these ..... digrams please
