Using these string lights is a breeze. First, insert 3x AA batteries into the battery compartment (batteries not included). Then, find a place to hang the lights according to your needs, like around a wedding table or on a Christmas tree. Turn on the on/off switch, and enjoy the soft white light. Remember, these lights are not waterproof, so don't use them outdoors in wet conditions. When not in use, turn off the lights to save battery life. If the battery runs out, simply replace the batteries to keep the lights shining. And that's all there is to it! Have fun decorating with your new string lights.
