The delivery arrived four days before anticipated. When the box was opened, 16 individual boxes but no instructions. I'm probably a little dense but I contacted the seller on a Saturday and received a response within three hours! there is a white plastic stick contained inside one of the individual boxes. Use that stick to turn on the lights and then allow them to charge in the light. The enclosed hardware is probably best used for asphalt and/or concrete. for would I used brass wood screws, attaching light to steps and hand rails. At three o'clock this morning I took a peak outside and was amazed as the efficient light coverage. Every light works just as anticipated.
