    I have one tail light that is much brighter than the others. I noticed both filaments are lighting up rather than just one. Just for fun, I put a 1156 with one filament in and that bulb still lights up brighter than the others

    If both filaments are lighting, you have a problem either with the way the socket is wired, or the socket itself is defective.

    Are you sure you have the correct bulb for the correct socket? 1156 bulb goes in a single element single contact point socket. ll57 is a dual element bulb that goes in a duel contact socket.

    Probably a bad ground causing a back feed through the brake side of the filament.
