My brake light is messed up.
My fuzes are good. I've checked the parking brake several times; it's not On. My brake fluid is good.
I can't figure out why it's on. It usually will turn off while I'm parked. Then it comes on at random times while driving. Why?

Brake switch under the dash has worned out.

Is that something that I could probably fix myself or should I take it to a Toyota place? I've never messed with the electrical system of a toyota before.
