Where is the best place to find bubble lights?
Regarding your Bubble Light question, here's an Amazon link that looks worth checking out:http://www.amazon.com/gp/product/B00827 ... UTOE436W27
If you're looking for lights for an existing have an existing light strand, you need to check to see if it's a C6 or a C7 strand. C7 is more common for bubble lights, I think, but I've seen C6s. C7 is the most common night light bulb size, if that helps.
Obviously if you want vintage bubble lights, you'll probably try e-bay. Just make certain that the shipping charges aren't ridiculous and they allow returns if they ship a defective or wrong item.
