The Solar Lights for Outside by Nature Spring provide unique, welcoming lighting that makes a wonderful addition to any backyard or patio area. The solar powered outdoor lights soak up the sun's energy during the day and automatically turn on at night, requiring no electricity or plugs for hassle free use. The rope lights also feature eight light modes (combination, waves, sequential, slo-glo, chasing/flash, slow fade, twinkle, and steady on) to create the perfect atmosphere for any backyard, party, or wedding.
