This is a set of 5 bulbs. They light with a 9 volt battery, we had no other way of testing them. The liquid moves freely. The particles move with the liquid. The bulbs are 4 1/2" from tip to base and roughly 1 1/2" fiameter at the saucer. There is a spot of scratched plastic on each of them in the same spot, maybe they were attached to something. We will include a light that has no liquid left but does light up. We will include the untested strand with Bryant embossed in the plug, we do not have enough bulbs to fill the strand, so it will not light the bulbs. If you would like additional photos or information please message us.
