Use our black rubberized two prong plug with our string light cords, light socket lamp holders, and metal hook to make a custom string light. You'll need to use this plug to attach to one end of your string light cord to plug in to your outlet. (The other end of the cord should use our metal hook.)
Note that this plug is NOT water resistant and if used outdoors you MUST place it inside of a waterproof or waterresistant boxed outlet.
