The lift gate seems to have a sub panel that could be popped out. It would be ideal if one could pop in a LED light fixture (designed for this lift gate or fits by happenstance) that is switched on off / automatically, so as to provide light when needed and turn off automatically so as to not deplete the battery.. Does such a unicorn exist? I would think I am not the first to look for such a fixture. Photograph of said sub panel in the lift gate
I followed your suggestion last month. I neglected to mention in the the original post that I would like to wire power in to the light.

Incidentally, I do have another set sitting around that I never got around to installing, and I'd be willing to let go of it for $20+shipping.
I added a switch so you can control the lights separately from the hatch / interior lights. Rear luggage light connector? | PriusChat
Would be nice if the switch would turn off automatically after a 15 minutes or when the trunk is closed. Unicorn?
For reference, I believe those two pop-out panels are for access to the license plate illumination LEDs.
