HELP!!! My headlights flickered on and off while driving, what’s wrong with my baby??

Hi all! So, I’ve had my 2001 PT Cruiser for almost 8 years now. It has 160k miles and runs like a champ, HOWEVER, tonight my headlights flickered on and off really quickly, went completely dark for about 30 seconds, then they started up again. I live in an area where there aren’t many street lights so it was pretty terrifying.

Lately, the airbag warning lignt comes on randomly, and sometimes all of the warning lights on my dashboard light up as well.

I’m worried that something might be seriously wrong with my car. Is it at the end of its life (ie. a super expensive electrical malfunction), or does this sound like an issue with a fuse?
