Check fuses, If brake lights do not work, transmission will not shift out of park. Brake light circuit is common to shift interlock. That's why you must step on brake to release interlock prior to shifting out of "Park" If stop lights are not working interlock will not release.

The brake light in the dash would be on because the emergency brake is on. If you mean the brake lights in the back, this would be because you are pressing the brake peddle or something is broken.
