lost low beam and driving lights

started my 11 up last night, had no low beam or driving lights, they were on but about as bright as a bic lighter, high beams worked fine. now this am went checked and they came right on ? now I did change to LED bulbs months ago on these but been fine any idea's ?? thanks Rob

Put the old lights back in and let us know what happens.

ok, tracked this down to trailer towing, if I have a trailer(2 different ones) connected and drive at night, no headlights or driving lights, unplugged trailer, restarted vehicle 3 times, still no lights(very very dim) let sit over night back to normal...?
