L.E.D. turn signal Issue

[BIGGPIGG4x4]

I tried installing my 2 color L.E.D. Turn signals in my 11, but the white l.e.d.s would flash on and off when I first plug them in, then nothing. The orange would flash with turn signals and hazards on. but couldn't get the white to work. Thru the bulbs in my dads 7.3 and the lights work fine. Anyone have any ideas?

Sounds like the same problen that we had trying to put them in my sons Dodge Ram. They confuse the computer, I think the solution is to add a ballast resistor to each of the parking lamp wires.
