Replacing the license plate lights

It looks like this could be a lengthy job, I can't seem to find any YouTube posts of this being done, which makes me think perhaps it isn't done that much on a 7 year old Prius- yet here I am needing to change the lights. However, I will check to see if new lights work with existing wiring before taking off the Back Door Outside Garnish

I was staring at this job with the back door trim removed and looking at those 10 bolts thinking that they should be removed, but it was getting dusk so I stopped. So the steps are pretty much
1. remove inside trim
2. remove bolts that hold the outside "garnish"/trim
3. remove the outside garnish/trim?

This would be a good time to replace those clips- does anyone know the part number?
