Fiat Special 124 1973 headlights. They're not turning on, does anyone have

[College student]

any idea what the problem might be I'm pretty sure the lightbulbs are still good, and the switch works, I think. If I turn it to the halfway point the fog lights do come on and the inside speedometer light comes on, but when I turn it to the full lights nothing comes on. Any ideas?
I'm pretty sure I don't have a manual....

i have a 74 124 sport it sounds like the switch seems to be working but it might still be bad and i would check the wiring from the lights up that switch may be hard to find. and do you have a manual? also pull the switch and check the connectors inside may be burnt.
