Rings (A Classic Reprint)

In this somewhat blurry photo are two cereal premiums from my lost youth. On the right is my Lone Ranger Silver Saddle ring. It has a gold saddle, so maybe I have the name wrong, but the ring itself is silver. On the left is one that, I'm ashamed to admit, I can't recall the name of. Part of the name is "signal ring," I'm almost sure. The curved part you can see at the bottom of the ring held a small battery, and you could use the ring (that's the original bulb) to send Morse code, or at least that was the theory. You might be able to make out the scales of justice on the left hand side of the ring. Maybe that's a clue. I think the ring might be connected to Captain Midnight, but I'm not at all sure. Any help?

Late-breaking news. I should've looked on eBay before posting. Here's the signal ring, which might not have been a premium after all. And here's the Lone Ranger Saddle Ring (no silver; I guess I was thinking of the great horse by that name). I don't have the filmstrip with mine.
