I purchased the USB led light to use to decorate with. They are 33feet long and have 8 different modes to change the color to what you like. There is even a timer and dimming switch on the remote. It comes with everything you need and instructions. I am going to put them in a wine bottle to use as a nightlight. They are a little smaller then what I thought I was getting. They can be used indoors or outdoors. And how ever or wherever you would want to decorate.
