For the outer ones, its pretty easy. Open the panels from inside, loosen 2, or 3 bolts from each side, disconnect the cable connectors, and push them out, give it a firm push, because the adhesive tape sticking. The inner ones, it is a little tricky. there are 2 small panels from inside of the lift gate, first you need to pop it open with a small flat screw driver, then you need to loosen 1 bolt on each side, now you need to separate between the lights and the panels because again the adhesive. Be very careful, you don't want to push it out too strong, if you look closely you can see the 2 hooks from the outer side of the inner lights hooked them to the lift gate. After you have the adhesive separated from the panels, push the lights towards the sides of the truck to unhooked them, don't push them towards the back, because you will break the hooks. I hope i remember the process correctly.
Have fun and good luck.
