For those wanting to replace the rear overhead dome light with a better looking white LED. I can't recall if there is another how-to thread on this, but here you go.. Sorry there aren't more pictures. I didn't think to write this until half way through.
You'll need a standard 194/168 type LED replacement bulb. I got mine on amazon, but I see them in auto parts stores now too.
I've done this on a 2013 Limited, and 2017 Sport, both with the dual moon roof and a single overhead dome light above the center of the third row seats. I'm not sure if it is different in other years/trims. The light still fades out when turned off or when doors are closed (called theater lighting), and it does turn off completely.
I'm willing to do the conversion for you if you ship yours to me (for a small fee). PM me if interested. I'll answer any questions in this thread if you need help doing it yourself.
1) Pry the dome light assembly out of the headliner. I suggest prying from the forward end of the assembly since the rear end connects to the wire harness. This takes a lot of force. It's going to hurt your fingers and its going to feel like you'll break something, but you wont. Once it's out, unplug from the wire harness.
2) There are 4 tabs holding the circuit board to the plastic assembly. Use a small flat-head screwdriver or two, and pry the circuit board from the assembly. (Circuit board already removed in this picture)

3) This is the delicate part. You'll see a small white 1/4" square with a yellow dot in the middle. This is the stock LED. I used a small flat-head screwdriver (and I mean very small - think eyeglasses screw size) and a small hammer to chisel out the LED. All it takes is a gentle tap straight down near the edges to break chunks off. You'll be nervous, but it works. Remove all of the LED to reveal the two metal contacts below.

4) Take the new 194/168 bulb and pry back the two wire contacts. Then, cut off the plastic base. You'll need to remove the base in order to solder it easier and allow it to lay more flat once installed.

5) The LED needs to be soldered to the correct contacts in order for it to work (Positive/Negative). Take the bare circuit board back to the car and plug it into the harness. Open a door so the dome lights turn on, and touch the two wires from the LED to the contacts on the circuit board. If it lights up, GREAT. If not, reverse the wires. I used a red marker to denote which contacts go with which wire.
6) Take the circuit board back out, and carefully solder the new bulb wires to the contacts on the board. Leave enough room to bend the bulb flat towards the rear of the board (towards the wire harness end)

7) Take the plastic assembly and cut a notch out of the silver shroud that surrounds the LED bulb. This is needed in order to slide the new LED in when clipping the circuit board back to the plastic assembly. I considered just removing the shroud, but it helps direct light downward, and looked better with it in.

8) Carefully clip the circuit board back into the plastic assembly, and then install back into the vehicle. You're done!
