just replaced the bed in my 2003 f150 . when i did, i replaced the tail lights with LED lights. now my headlights will only turn on but wont turn off. i replaced the fuse and manual light switch. same issue is still happening. i have to unplug the battery to turn the headlight off. also the night time running lights wont work on the new lights. any suggestions

often putting on led lights messes up the wiring unless you put ballast resistors on with the leds, try that first
