It has been brought to my attention all Christmas lights were not tested prior to being listed.  I apologize for this error.  I am in the process of testing each listing and I will update the title and condition accordingly.  If there is a set you wish to purchase, please message me with a link to the item or the item title so I can make it a priority for you.  I apologize sincerely for this inconvenience and I thank you for your patience as we work through these listings.
