I've been running the DDM 35w fog (slim ballast) lights for about mouth now. Install was very easy plug the stock plug into the ballast two wires going to the lights. The night I instilled them I turned the key started the truck the radio came on clearly, turned on the lights and the radio on low volume has an engine whining though the radio. The stations that are faraway that came in clearly before are blank nothing there, no sound at all. The stations that came in very clear are quieter. I can switch off the fogs and the radio is fine. I’m I missing something? Or is the ballast feeding back though the wiring? Please help…….
