I am so happy with this string of lights. They are 16 ft and have a nice thick plastic coating over the lights so they are protected from the weather. They have to be plugged into a wall so you need to start close to an outlet or run an extension cord. We ran them along our stairs so it give a little extra light at night and they look pretty with the snow on them. Plus with the remote we can choose any color we want by a press of a button.
