If you are having issues, (it seems quite a few are), many may not be aware that this is causing a fault code to show up on their BCM. (Body Control Module - the module that handles headlights and such.) There's no check engine light or anything. It's not a powertrain related fault. But it is in the BCM memory. Every time my headlight (low beam) would go out, a fault code was created in the BCM. I forget the exact codes, but could get them if needed. I also had two faults for high beams as well, but they still seemed to work. While this isn't a big deal now, it could be later. While trying to come up with a fix for my problem, I stumbled across a section in the service manual regarding BCM outputs. The BCM is designed to shut off a transistor output in response to a short or ground. But, the BCM outputs are only designed to handle a finite number of faults. After so many events, the BCM will lock out the output. The only solution is to replace the BCM. Now I'm not sure about parking and turn signals, but I would think it would be no different. Just something to throw out there for those who just keep trying to deal with these issues.

I seriously considered upgrading to OEM LEDs, but reading the forum and this thread it souds hit or miss so far and I'm now hesitant spending couple thousands of $ ending up with electrical gremlins

One code that I never figured out, that was also present, was B1446. That code stays in my BCM at all times and won't clear. Maybe a ford guy on here could get me the meaning of that one. I searched and found that it may be HVAC related. Doesn't seem to be related to lighting. My heat and AC seem to work fine, so I'm not concerned. But it all may be related somehow.

No issues so far. It's only been one day so I will edit this post if anything changes. But I've tested them out extensively.
