These solar pathway light set includes four solar lights that you can place almost wherever you choose. Place them along side a garden pathway or driveway; place them amongst your flowers or shrubbery; use them to highlight a pool area or a patio. As long you place them somewhere that gets sunlight, you can expect some excellent nighttime illumination effects from these solar landscape lights. How do they work? Well, basically, a small solar panel located on the top of the light collects sunlight and converts it into electricity. This electricity is stored in high-tech NI-Cd batteries. At dusk, light sensors located in the solar lights recognize the coming darkness and automatically turn the lights on. Then, at dawn, the lights turn themselves off.
