This listing is for 3 sets of lights.
The first strand is 38 feet long.
The second strand is 10 feet long.
The third is 10 feet long.
Only one socket in the 38 foot strand is broken.
Some of the lights are original and not replacements and to the best of my knowledge you still can get replacement bulbs.
The lights have been well taken care of so there are no strands that are frayed so if you would like to have a 50's Christmas, all you need to do next is get that lamp to go in your window.
