Christmas tree lamps. This is the type of light bulb. It's quite old. Power tested. When plugged into an outlet, it lights up and then starts blinking after a while. Some of the lamps are burnt out, so this is a junk item. For those who can replace/repair it, or those who don't mind using it as is. The item you will receive is the one in the photos. Will be shipped in simple packaging. No price reduction.
