Because these mini green-wire light sets don't have a bulky end connector -- and therefore can't be hooked to other light strands -- they are perfect for any lighting project where clean presentation really counts and you don't need much to get the job done. Buy non-connectable mini lights for your crafts or to light up wine bottles or glass blocks. These mini lights are available in 10, 20, and 35-bulb sets and are UL listed for indoor and outdoor usage.
