I had to replace my brake pedal stopper when I discovered my brake lights were staying on.
I just replaced my car battery.
I made sure the brake lights weren't staying on because of the fuse by honking the horn and hearing the sound. The horn and brake light are on the same fuse #15 indicating I did not need to update the fuse.
***Make sure to push the white stopper in the hole so it snaps! Mine kept falling out.
