I installed switchbacks with resistors but when I turn on the lights the white drl led don't come on but the amber works when I turn on the flashers.
OR...... We do have 2 wires to the blinkers, but the wire to the running light function of the turn signals only sends 10v and that is not enough to light up the white LEDs in the switchback. A simple 12v automotive relay x 2 would easily fix that. You would just use the 10v signal to close the really to send 12v to the white LEDs.
