The enigma of streetlight interference (SLI), has been recorded in various parts of the world. Many people say they are able to turn off the streetlights just by walking under them. Is this an explainable electrical phenomenon or the product of unknown energies? How can we explain that a street lamp nearest to a particular person suddenly blinks out, turning on again as soon as the person passes it? If it happened once, we could easily explain it as a coincidence, but what if if it occurs over and over again just to that particular person then it is an enigma? What if that person has that effect on other lighting, and appliances? The true reason why some people cause streetlight interference remains a mystery. Tonight we will talk about SLIders, and the energy behind the legend.
