The new Brightech Ambience Pro Solar Extension Cable can lengthen our Solar String Lights. You no longer need to compromise on the placement of your solar panel or where you hang the string lights. Up to 6 feet of extension and very easy to install. Plug one end of the wire into your string lights and the other into your solar panel. Place your solar panel in just the right spot to power your string lights with the needed sun exposure. Light up your yard, patio, or deck! (Note: not compatible with other brands of string lights.)
