Sounds like you had a massive short that probably damaged some of the wiring that leads to the taillights. You'll want to trace the wiring back from the taillights forward to see if you can find any melted wire and fix as needed. There may be a fusible link from one of the main power wires of the fuse box that is blown as well.
