headlights won't work

[dixiethecustomcamper]

Hey everyone, looking for a little help. my headlights will not turn on when I pull out the light switch. This just happened recently. Prior to this the truck always had finicky lights and sometimes they'd go off if you put the high beams on. This also worked the other way as you'd turn the lights on and they stayed off, but press the high beam switch and they'd come on. having no headlights is dangerous and being unable to drive it past about 8:30pm is disappointing. truck is a 1968 gmc custom camper 3/4 ton. I checked all of my fuses and wiring today, everything seems to be in working order... any ideas? could there be a switch somewhere that's worn out or blown? thanks!
