2010 Ford F-250 Head lights No low beam only high beam. Here is how I reset it at the smart junction box on driver side kick panel. Make sure park brake is off and I have a plow harness on, so make sure to switch to truck lights not plow lights if plow is off. Also the day time running lights won't work. Update on the cause. I have a boss plow which the headlights draw 6 amp. on each side, the truck lights draw 2 amp. on each side. With both lights on the truck it draw 4 amp. the plow draws 12 amps. So when the left side of the FET ( witch is like a relay in electronic ) goes out the right side draws 12 amps and kicks off the low beam. I had to buy a new smart fuse box. The high beam also runs the low beam but it has a relay from the battery to the low beam wire lowering the amperage on the circuit. Hope this helps. It worked for a year then I had no more low beam. I ended up changing the smart box.
