Both headlights died

My sister's Prism's headlights both died. She said first they dimmed and then they both went out. I had her check the fuses, hoping there would be just one for both headlights and it would be an easy fix but there was one for each and she checked them and they were both fine. I had her look for a relay or something that said headlights on it and she found one that said "head" but I don't think that is it?

What are some of the simpler things she can check? I can't exactly go help her since she is in TX so hopefully I will be able to help her over the phone.

Thanks for the help.

what year is the Prizm ?

Sorry for my lack of attention on this thread. I talked to her recently and the problem has been fixed. Thanks for the help.

There might be some issue with the relay so the headligh dimmed and then gone dead.

Check the relay otherwise there will be some trouble with battery connection.

Don't drive in nights without headlight!
