    So they did work after you changed them. Correct?

    Has the car had any other recent changes made?

It has been my experience that the type of problem you describe is usually caused by a bad ground at one or more of the lights, or by a bad chassis ground. I suggest you first ensure that the battery, chassis, and engine grounds under the hood are good. If they are you might try pulling one lamp at a time to see if you can find one that when pulled, the rest work normally. If you find that lamp, your problem is there. Good luck

The interior brake light on my console is illuminated.

The brake warning light tells the driver the parking brake is on, or the fluid in the hydraulic system is low.
If the parking brake is not on, and the fluid level is ok, it could be the parking brake switch or the fluid level sensor.

Brake lights stay on

There is usually a contact switch high up behind the brake pedal arm. If this has become jammed or dislodged this maybe the cause of the problem. Simply inspect its mode of action when the brake pedal is pressed. If needs replacing a few dollars will be all that it costs

Where is the brake switch located on a 1990 geo prizm?

Brake Light Switch The brake light switch is located at the top of the pedal arm. It is the switch which turns the brake lights on when the brakes are applied. The plunger type switch is held in the off position by the normal position of the brake pedal; when the pedal moves during brake application, the switch plunger moves forward and the brake lights are brought on. The switch is almost always the first place to look for the cause of the brake lights flickering over bumps or staying on without use of the brakes. If the brake lights fail to work with the brakes applied, check the fuse first and then check the switch.
