In the end, I believe the DTR function is messing with the relay and ballast. It pulses a signal to the DTR's and I think it is underloading the signal to the ballast and creating issues. I have never run into this before and have installed 6 of these kits before. Be that as it may, I'm not willing to mess with it. I went out and bought some Sylvania H11 Powersport LED's. They had good reviews and installed easily. They put out a very nice crisp white light and have a sharp cutoff. Not as good as a true HID OEM light, but far superior to the Halogen lights that Ford gave me...
