2012 JKUR with Trucklite LED headlights and anti-flicker harness, stock fog lights with replacement LED bulbs. I've only had the Jeep a year or so and I'm pretty sure the previous owner spent some time on the Oregon coast/dunes with it (had an Oregon dunes/ORV permit), but there is no major rust to the frame or body, so it looks like it was well maintained.
Went wheeling at the local dunes (Juniper Dunes ORV park) a couple of months ago and started having headlight issues. One low beam quit working, then the other low beam quit, but both high beams worked. By the time I left, only one high beam and the fogs were working.
I figured I had just rattled something loose, so the next day I tore everything apart. Both headlights worked fine both high and low beam when jumpered straight to the battery. Both headlights worked fine with the anti-flicker harness jumpered straight to the battery. Was getting proper power from the factory headlight harness. So I fiddled with the pins on the anti-flicker harness, cleaned them and used some dielectric grease and things started working again.
Now a couple of months later I have one or both headlights going in and out and now this morning one of the foglights (same side as the malfunctioning headlight) is not working either. I'll run the same troubleshooting routine again, but it is starting to look like an issue somewhere in the factory harness.
Has anybody seen anything similar? Any hints on where to start testing/digging for issues?
I'm not too sure about the small 3-pin factory headlight plug and may just cut it off of the factory harness and solder the wires directly to the anti-flicker harness and see if that helps.
