Brake and parking lights Stay On

I have an 89 Jeep wrangler yj 4.2l and even though my jeep isn't running both the brake lights and parking lights Stay on, even with the headlight switch removed.. Brake pedal switch is loose, and when I depress my brake pedal my brake lights go out but my parking lights remain on, and a square black box saying alpine with a adjustment screw "min - max" mounted to my firewall also lights up a red led light also. The led light goes out once l stop let off the pedal. Any ideas, suggestions?
