I'm having problems with my headlight kit from DDM. I installed the drivers side first, reconnected the battery and turned the lights on to test it and all it does is flicker like a strobe light?? The stock bulb in the passenger side still lit up fine. Double checked all connections and even tried another ballast/bulb and it still flickers. So, I decided to hook up the passenger side and test both at once and boom, nothing, no headlights at all? I've triple checked all connections to make sure they are correct and still can't get them to work with both hooked up or quit flickering like a strobe light with only one side hooked up. Anyone have any ideas on what the problem could be?
