I really struggle to believe the previous owner decided to change out all the bulbs in the rear to non-LED. The previous owner was a retiree that didn't do any mods other than window tint.
Any theories as to how this would happen? Maybe being a final edition, Jag ran out of rear LEDs, lol.

😅 Possibly. Come to think of it, I believe my 2016 was the same way 🤔. I did a full LED swap...and can't recall having to do the front "touch" LEDs upfront.
I have opposite on my XJL. Previous owner fitted white (and very bright) LEDs on rear dome light but front ones are still original warm non-LEDs it seems. I was thinking if all ceiling lights could be changed to white LEDs? Easy to do? I have indeed seen kits being sold on Ebay and Aliexpress for XJ interior LED bulbs.
When I did an LED swap of the interior lights of my 2012 XJ, I found that the rear lights would be very dimly lit at night and you could see them in the rear view mirror. This may have been the case and the driver simply opted for the easier fix of putting the original incandescent lights back in. As it was explained to me, because the lights are touch activated, there is a very minute current that flows at all times through the light lens and when you touch it, the current changes and activates the lights. In the case of LEDs, unless you have a resistor built into the LED, this "touch current" is enough to make the LED glow slightly.
So, if you do upgrade your rear lights with LEDs, you may need to find some LEDs that have a resistor built into them to "simulate the current draw of an incandescent bulb. This resistor drops the voltage low enough that the LED cannot glow. dimly.

Looks like Jag learned their lesson with those finicky touch lights and switched to regular button activated lights by 2019, so I don't need to worry about resistors.
Just noticed this 2016 XJ R-Sport that sold on Cars and Bids in March has the same LED bulbs in the front and regular bulbs in the rear as my car. So that must mean Jag had been doing this for a while and my car is stock. I am tempted to just change the center bulb in the front to match the rest because the only LED bulbs are the front dome and map lights, and the map lights don't come on with the door opening. I am over the LED thing, so it's a lot less bulbs to change to get everything to match when a door is open.
Lots of changes compared to my 2014. Surprised that put that much effort into a car they knew was soon to be discontinued?

True, but the parts that got changed in the XJ are probably parts that are being used in other Jags that were not going to be discontinued soon, like the XF and the F-Pace.
