2018 F 150 Low Beams Not Working

2018 XLT. Installed GTR Ultra Series 2 LED bulbs from Headlight Revolution in the stock Ford headlight housing. I also installed the suggested anti-flicker harness between the ford connector and the new LED bulb. https://www.headlightrevolution.com/...A_2?quantity=1

All was working well until last night. I pulled out of the garage and my low beam lights will not work. My high beams work fine. I am finding conflicting information online about possible fuses causing the issue, relay causing the issue, other...?

I'm at a bit of a loss and wondering if anyone has has this specific issue and the fix?

Any questions about my situation please ask away. thanks!

Return it to stock and see if it works correctly or not.

If it does, you know the problem is in whatever you bought and installed. Call them for help.

If it still doesn't work, then we can try to help.

Here is the latest - I removed the #4 fuse - 60 amp "Body Control Module", replaced it and now my headlights work. It was not blown. Seemed to need a reset.

I'll monitor for the next couple of weeks and provide an update to the group.
