I only changed mine to LEDs before I got the mindset to say screw it. I upgraded the trunk to LED in 2018, same with the backup lights (which made somewhat of a huge difference in lighting while in reverse). On my 2018 Explorer, I left the lights stock except for the reverse lights. BTW my Explorer license plate lamps (same as the Fusion Sport design) already has moisture on the inside. I wonder if it is because of the heat generated from the incandescents drawing in moisture somehow through the seams of the lens housing...I'm not touching my plate lights for two reasons. One my first Fusion I had, had one that never worked from the factory, don't want to mess with the tiny things, two it doesn't benefit me in any way to have it brighter.
To answer previous question, no the trunk is still incandescent on '19s, forgot about that one.
