I have a 2018 STX package F150. Do you have to go on Forscan and change anything when putting LED lights in tail lights and headlights ?
I have a similar story. But the problem is that I don’t remember what I did, alas.At least on the 2013, Tail and headlights aren't affected by swapping to LED's. It's when you start swapping out blinkers that you get the hyper flashing of the blinkers (Ridiculously fast). There's a setting in forscan that I had to change when I did my blinkers. Forgetting exactly what it was called, but I assume the logic is the same in your newer truck. So, no, if you're just swapping headlights and tail lights/brake lights, you should not need to mess with any settings.
