I am not a mechanic, so follow directions at your owe risk. :) I changed out my 2006 Toyota Tundra Tail Light Assembly by the following. Opened the tailgate and used a 10 mm nut-driver to unscrew the two screws holding the tail light fixture in place. Gently pulled tail light fixture away from the truck to disengage the two guide pins that go into the truck bed body. Then twisted the plastic light bulb retainers counter-clockwise and pulled the light bulb and retainer out from the light fixture, for all three. I couldn't just install the replacement Tail Light Fixture with the currently installed wiring harness because the top (reverse light) light bulb retainer diameter was too large to go into the new fixture. Therefore, I needed to then remove the wiring harness also.
