Jeremiah, I know the SE editions had the overhead displays. A kid I knew back in the '70s got one and it had the same thing as in the picture. When he first got the car, one or two of the lights were burned out and he had a hard time getting the thing apart to replace the bulbs. Eventually, though, he got everything to work so he could look up at a sign to see if a door was open.
Looking at the pic of the side of the Challenger, it appears to have the SE badge on the C pillar.
