Usually, each light is protected by its own fuse. It would be unusual for both lights or both fuses to fail simultaneously. However, both lights are controlled by a single relay. I would put my money on the relay.

Attn all motor people,
If both your headlights go out at the same time, which is it most likely to be, the bulbs or a fuse? Which would you do or check first?
Thank you.

Wise guy, it is not OP error, lol.
The relay is a fuse as well? Will Auto zone put it in you think?
Happy new year Don.
(this is son's car, so not sure of the model) It is little and red. lol.

could be a relay. my grandpa drives a 2000 something mercury crown vic. all lights go through a module under the middle of the dash. Module to replace (because they say it is non repairable) is almost $600. I fixed it for $5 bucks after I took it apart and resoldered a relay. This time I used a better relay and remotely located it so it can be replaced if necessary.
A relay is not a fuse. Usually the relays are located in the engine compartment in a self-contained compartment with a plastic housing. You'll find fuses in there as well. If you look at the inside of that plastic cover it will show you where the relays are located.
The guys at the local Autozone should be helpful in identifying and replacing the relay.
Auto Z will check it out for free.
If it is American made depending on the year then the Rear Tail lights may be out also.
If it is a fuse then there is a reason that it blew.
Don't pay someone to do a job fast, when you can do a half-fast job yourself.
did he install a radio recently? maybe cut some wires under the dash he wasn't supposed to? lolseen that a lot when I used to install car stereos, alarms & car starters when I was younger.
I am doing my mom thing.I will tell my son about the relay, thank you so very much. I did ask him, about the back lights and he said, they are working, turn signals, the works, just the headlights aren't working. If a fuse, wouldn't a fuse blow just because the fuse went bad? Bad fuse?
Oh, boy... you might had hit on something with the radio. I will have to ask him about that one. He only has a small cassette player in this car, and, he wanted a CD player.
He was talking about installing one.
I bet he did.
His dad could build a car, a hybrid, better than a car manufactuer. He could fix this in a heart beat. lol.

Nope... he didn't do a radio or CD player, still listening to the cassettes and hating I am sure, every minute of it.So, scratch that idea.
I wish things while I was growing up were different for girls with fixing cars. The interest was not encouraged for it. If I had a daughter, I would really encourage her to take classes in mechanics. At least to do the basics.

The headlights that I know have to be on a relay that automatically resets, so you get a few more on off cycles of the lights at night so you can get off the road. No fuses for Headlights anymore. Probably a bad relay.
What did he do ?
He must of had a Girl in the back seat, Smashed a wire from all the bouncing, Blew the fuse, and could not drive home.
Sounds like a story that my boy would tell, After being out on a date with a Hot Chick.
Ask her what really happened. She may say, "I just hit the gear shift knob" But she knows what really blew his fuse...
