91 headlights are out

While driving home from work one night i went to turn on my brights and my headlights went out. All of the lights are out, the headlights and the tail lights. Any help or advice would be great.

check the fuse

Hey just posting back finally. If I remember correctly (this post is old) it was one of the in line fuses up front that was failing. All I did was replaced the wire with a thicker wire. Probably not the smartest idea but it did work and ran fine.
