A 4 channel 8 function light controller for Christmas lights. My mom had gotten a set of 100 lights with this exact controller on it. We had them for a few years, but they finally broke. I decided to see if I could track them down, and found this. It's the same thing, except you get to hook up whatever lights you want to. I honestly might get two or three for the future because I adore the "Slo-glo" setting. It's so beautiful. In the video it starts at around 1:34. I remember sitting in the living room late at night watching them as it was snowing outside, listening to Bing Crosby. It was amazing.
