Long story short, was working on the car with a buddy and something hit the driver side tail light and it shattered, creating a big hole in it. Already ordered a new replacement, but not sure how to replace it? Do I have to take the rear bumper off? I want to make sure I replace and install it securely so there won't be any moisture or any leaks of that sort.

 

4 bolts in the back and it comes right off. No need to get the rear bumper off.

 

You get to it from inside the trunk. It's really easy.
