Changing a 2005 Honda Civic Taillight Lens (aka: removing your bumper)

I recently had to change out one of the taillights in my 2005 Honda Civic Hybrid, and was surprised that it was more complex an operation than expected, requiring the partial removal of the bumper.  It wasn't really difficult, but documentation was sparse, so I thought I'd share the experience here for anyone else encountering this situation without a friendly guide.

The steps laid out here aren't necessarily in the "correct" order, but this is the order in which I operated.

Step 1 Step One: In the trunk

Expecting the best, I began in the trunk.  The first thing to do is get in behind the trunk lining to access the back of the light.  There are two little plastic plugs you can unscrew.  Then just pull the lining clear of your work area.  This part is described in the owner's manual, because this is also how you get in there to change the bulbs.

Once the liner is out of the way, it's pretty obvious what needs to be done.  First, unplug the cables, then unscrew the nuts from the three posts holding the light lens in place.

At this point I started pulling on the lens, pushing on it, and was about to start prying, when I decided that there must be something more to this.  I checked online, and discovered that I was going to have to remove the bumper to access the final screw.  That's when I decided to begin recording the process.
