It seems that Ford removed the lighted PRNDM, and it looks like it may have happened in stages during the 2018 production year.
I don't have any particular knowledge on the subject, the below is just based on my observation.
Early 2018's have lighted PRNDM. At some point (SSM 47312 indicates 17 Jan, 2018, production date as the cut off) Ford stopped putting the backlight in place but continued to use the translucent PRNDM equipped trim piece. It would be possible to add the backlighting to these vehicles. At some later point (no date found on that) the center console piece was changed and the letters painted on the console, backlighting these would not be possible at all as originally configured.
My very early March 2018 build 2018 (802 + tech package) has the painted on letters, it simply could not ever be backlit as originally built.
