What happened to my lights?

[mastx]

Here's the story. All my lights(dash, parking, headlights,reverse) were working fine. Then last night all of a sudden, I notice my dash lights went out. My headlights and signals were still working so I was able to drive home last night.

Now, only the headlights(both dim and bright) and the signals(although they are blinking very fast) are the only thing working.
The dash lights dont work, the brake lights dont work, the parking lights dont work.

Since some of the lights work, I don't think a bad ground is the problem. My first guesses are a blown fuse or possibly the light switch.

Is there a way to know if my light switch went bad?

Any one ever have something similar happen? Any ideas would be of great help!!!

Thanks
