Sasaki,

An "idiot light" is any light on the dash, other than a guage that gives you an actual measurement (Like the oil level guage), that usually comes on to tell you about a problem *after* it has happened.

It sounds to me like you have a faulty contact on your emergency brake switch. It should be located somewhere in your cover boot. (I'm assuming you have checked break fluid level and found it to be normal.)

Just a thought... I'm assuming that your brake pedal feels normal during brake application and that your car stops normally.
