An eco-friendlier alternative to traditional holiday lights, these solar powered snowflake lights from GrandinRoad.com are made to glow without electricity in all kinds of weather. Even when it's overcast, the remote solar panel absorbs enough energy to make the snowflakes sparkle for up to 8 hours. A cool feature your kids will love: Each light-up snowflake also changes colors, cycling automatically through seven seasonal shades. $59 at GrandinRoad.com.
