Ah-ha! I was blind, now I can see.

When I had looked a month ago I entered the model of car as "Chrysler 300" and found the sills. But when I've looked recently I've been entering the vehicle as "300C" (just being technically correct), and thus, they do no show up.

Oops.

My 300C has stock brushed sills, but as far as I know they light up less frequently than Yul Brenner.
