break light on dash won't turn off?

I have a 03 tacoma trd pre runner, the break light indicator on the dash is always on and the dealership just says to bring it in. Does anyone know what the problem could be so I can fix it?

 

Low brake fluid, or E-brake is seized/out of adjustment.

 

The e-brake light?

Isn't there a switch on the rod connecting to the handle under the dash, so when you push it in, it turns off?

 

Thanks for the tips.. I'll check those out.

 

It ended up being low fluid. It was just under the max line but I've read that the sensor tends to be a bit touchy
