My sister gave these to me for Christmas last year, and 'we' decided they were too delicate for our country winds. But after showing them to Mom, 'we' decided to give them a shot. They are solar lights and change color - - and so far the wind hasn't taken them for a dangerous ride. After Bart put them up I commented "this is probably it for Xmas lights too?" and he seemed to think that was a good idea. So Thank You Barb - I love them - and wish I hadn't hid them in the basement for so long.
