2005 Chevy Colorado Replacing right rear turn signal bulb

Since I received no answer from this web site I did what I should have done first. I called the salesman that sold me the vehicle.

To remove the rear tail light cover Drop the tail gate, there are two screws to remove, one screw is located in the center of the tailgate latch and the other screw is located at the bottom of the lens. Removal of these two screws releases the tail light assembly.
