In this video, you can see how to replace the tail lights on a GMC Sierra. For this simple and quick operation, you need a T15 Torx wrench, a plastic trim tool, and optionally, a roll of tape to further protect the body.

First, open the tailgate, then remove the two screws securing the light using the Torx wrench. Use the trim tool to pry the light away from the body and pull it out, finally disconnecting the rear connectors.

Install the replacement by following the exact reverse procedure.
