Identifying the positive or negative wire in Christmas lights primarily depends on the specific type of lights. Most LED lights use polarized wiring, where one wire is smooth, and the other has ridges or markings. Typically, the smooth wire is positive, and the ridged wire is negative. In traditional incandescent lights, this distinction is less common, and using a multimeter to test continuity may be your best option for identifying polarity.
