I have HID's in both headlights and my foglights, I have never had a problem with turning them on.I have HID's on my car, and they virtually eliminate the need for my fog lamps. I tried to convert my fogs to HID, but they didn't turn out so well. I'm still looking for the HID Iceberg Blue fogs....but if I can't find them, I might as well get rid of them altogether.
the part numbers I gave you is for the P5. 03.5 MSP fog deletes come as a pair under 1 part number
