Antique Exhaust Tip Edison popular C6 Incandescent Pear Christmas Light Bulbs in Cobalt Blue and Emerald Green & C7 Ruby Red, and Orange - untested

popular I have no way to test these bulbs so I'm not sure if they work or not, though the filaments are not broken (look at them back lit). The color on them is quite amazing for these bulbs. They are rare to begin with, and even more so when they still have vivid color like these.

There are 5 ruby red, 2 cobalt blue exhaust tips, 1 emerald green exhaust tip and 1 orange/red

Excerpt from above site: The collector will typically find that American and German made colored lamps from this period are painted, while their Japanese counterparts are true colored glass.

I believe these may be the Japanese versions since they have no color loss. If the color was painted on they would surely be color loss after a hundred years.
