Media could not be loaded. These lights are MAGIC! The description fits them perfectly - they really seem to "shimmer". If you're looking for ordinary, regular flickering lights, then just go to Walmart. (I think that's why some people left such bad reviews.) And I don't mean that in a bad way. These lights are just different and I think they are MUCH prettier! I love that like most strands, the shimmer looks completely random and unpredictable. And the most amazing thing is that along with the shimmer, the whole strand very delicately, thinly and slowly "pulsesβ, which is why it flickers. At first you don't even notice it. My husband and I looked at them and wondered why they look so different and beautiful and here's why! I noticed that the reviewer said they don't flicker, but you just have to be patient. They look like regular filament when you first turn them on, but after a minute they start heating up and blinking. I've been looking for the perfect soft twinkling lights for years and finally found them! attach a video so you can see them.
