I did exactly the same thing for my 2020. That little bitty bulb was USELESS. I found an awesome LED strip that plugged right in, with a little effort. And when you do that you don't even need the plastic cover.
Here's what I bought. Great quality, much better than one I ordered from Amazon previously. The LEDs are encased in heavy-duty vinyl, and the adhesive on the back stuck perfectly to the metal in my trunk's roof.
