I think you have to pull back some of the trunk interior trim, not sure. You should be able to see how it's done if you take a look at the car. Should be easy.

Replaced trunk license plate lights: Eiko 104 bulbs.
O'Reillys does not carry the Sylvania 3652 and did not offer a cross reference to the Eiko bulb.
Finally went to NAPA to get bulbs.
After some searching, found one little reference to getting the housings out of the trunk lid. I read that the little plastic cover slides to the right and pops out. It's just not obvious on how to make it pop out,
but you'll get 'em. Slide the unit to the right and the left side pops up a little. Stick a screw driver wrapped with tape under the edge and pry gently until the unit pops right out. Then push in the connector tab and separate the housing from the wiring so you can take them into the house and pull the housing apart, clean it, and replace the bulb.

BUT....!
Getting the little housings apart was another challenge. But there is a trick. Take a very small screwdriver and push-pry the gray inside part inwards ON THE END WITH THE TWO SMALL TABS (each tab separately and VERY gently). Don't try the big tab.

Then, as the british car manuals always say, reverse the process to assemble. One tip though, when pushing back into the hole in the trunk lid, take that screwdriver and gently push in on that tab on the left to easy the housing back in.
Test your lights.
