Our lights are static, they don’t move or twinkle. However, an optical illusion is achieved if the wind moves it at all, it appears that they are.
There are other types (mostly for indoor use) that mimic actual stars or planets that do, but, they are not colored Christmas lights.
For these models just enjoy the way they just light up the house and trees.
The reason we chose not to make them move is that they are usually directed towards houses (including windows) and they could become annoying if they were constantly moving. Moving/ twinkling lights are also a hazard for people with epilepsy.
