Yes Kevin, this is Tappan Fabulous 400 gas range. I have the service manual for this, and it is maddeningly vague about those jewel lights, even though it gives exacting information about how to remove the toggle switches. From reading it, it appears that they come out from the front, but I'm not going to worry about it until we get the thing hooked up, because they may just work.
I love the jeweled lights as well. When I was in high school, I had a job of running the "city auditorium", (which was conveniently located in the high school), and it had a HUGE dimmer board each of which had a colorful jewel light, just like on this range. A few years after I left they replaced it with something more modern, which was a very good thing, but it would have been fun to have snagged some of those jewels.
