Headlights stopped working in the middle of the night..on a highway

This happened out of the blue last night.

My friends and I drove 40 minutes out to a mall, were in the mall for 4 hours, drove to a gas station--my lights were perfectly fine.

Halfway through the drive back home, I notice the road is hella dark. So I try to turn on my brights...and they dont work.

So im freaking the fuck out because we're damn near an hour away from home and its pitch black outside...on the highway.

I manage to drop everyone off safely but I literally had to use my hazard lights for lighting since I live in the middle of the woods.

My car is pretty old, it was my grandma's first--but we got everything replaced on it so theres no reason why the bulbs should have just blown out.

I love my Fiat so much--but Ive only heard bad things about them and I fear this may be strike two--right after my AC not being cold or blowing at all.

Im sure i can get my grandpa to fix the bulbs when its not hot outside though.
