I recently purchased 2015 Superduty. It has aftermarket headlights installed. I purchased factory headlights and installed them with new bulbs and they don’t work. It’s just like there’s no power to them. I reinstalled the aftermarket’s and they work fine. What am I missing here?
That’s a strange one. Are the aftermarket HID or something? Maybe being run off a relay? Wouldn’t make sense though. Did you have to wire in a connector?

You're probably gonna have to start following the wiring to see if there's anything spliced into it to control, or convert power for, the aftermarket lights and cut it out. I'm not familiar with LEDs, but the aftermarket HIDs usually have a power ballast wired in somewhere. Figuring out a wiring job someone else did is always fun.
