Had headlights, then high beam only, now nothing

they were working, then they weren't, then only high beam, now nothing. Got dash lights. I'll check the rest, to be sure. I think it is only the headlights, that are effected
Dont rule out bad bulbs till you have tested them. Long shot but maybe you are running to high a voltage an burnt out the low beam then switched to high beam and burnt them out as well.
