I recently bought a pair of LED headlights with the in-line drivers on them with a direct plug-in to my factory harness, the lights worked for about three weeks with no problem and now whenever my truck is running only one of the lights will work. If I turn my headlights on without my truck running both lights illuminate, does anyone know why this is happening and how I can fix it? I have tried a different set of bulbs and the same thing happens.

id do a relay setup no matter HIDs or LEDs. A never fail solution. It just relies on the OEM harness for just a signal. If they fail to turn on the relay a back up switch will turn them on.

I bet the truck doesn't like them directly plugged into the OEM harness. Screws with the computer. Or in a 3rd gen the TIPM module
