Default both headlights out at the same time

i didnt find much through the search. so

one night my headlight would not come on but the markers and rears did also high beams. a few minutes later they popped on by them self.
all was good for about 2 weeks then they went out again and not came back on.

i checked the bulbs, fuses, relays, wiggled wires, banged on em, drove down pothole roads and nothing.

driving at night by holding highbeam switch the whole time, at the moment.

any ideas.

does your drl relay click? swap it out with a different relay not needed at the moment(fuel pump possibly-just for test), it might be in the turn signal switch, ill try to grab the rest of the diagram 2morrow
