There are several EMs with similar features. I believe on "Flip A Card" and some other games, the name lights only in "game over" state. There's a blinking buoy on Gottlieb "Surf Side" that lights at "game over".
"Ice Revue", as mentioned above, has double lighting on the backglass skaters. If you notice, there are six different skaters under spotlights; two red, two white, and two blue. These correspond to the red, white, and blue banners under the kickout holes, and light the same as the playfield lights on those three banners, dependent on the 1-6 targets made. The same skaters illuminate with a separate lamp at "game over", preferably using flashing bulbs.
"Sing Along" and "Melody" have four pairs of carolers depicted on the backglass, each dressed in colors corresponding to the four groups of four colors that you try to complete when playing the game.
There are many other examples of this type of hidden feature which don't readily come to mind at this time.
