electrical system

Whenever I start my 92 maxima all the lights come on and they dont go off. Even the parking brake light comes on and I know the parking brake isn't pulled up. I think it could be an electrical problem but I have no idea were to start looking for it. Any help would be much appreciated.

Thank You in advance

The parking brake light could be telling you that your brake fluid is low. Not so sure why the rest of your lights are always on.
