Many times, you may have been walking down the street and then noticed streetlights begin to experience interference or even go out altogether. In all these cases, you always thought it was a normal occurrence or that the electrical current, or even the light bulb itself, was not working properly. This situation, in principle, is nothing unusual. However, it may be surprising that this event occurs more frequently, and even stranger is that it always happens to the same people.
Cases of this type lack a rational explanation and have been dubbed the SLI (Street Light Interference) Effect, which, literally translated from English, means "interference of street lights." This name was coined by Hilary Evans, an author of paranormal studies, to denote the supposed ability of certain people to turn on or off security lights on streets or buildings just as they pass by them. Those who cause them are called sliders (the English term for people who turn off their lights), while in several Spanish-speaking countries they are called streetlight switchers.
What is it about?
The SLI effect consists of the ability, usually involuntary, of certain people to interfere with the normal operation of street lighting. These events can result in lights turning off, on, or changing intensity when those causing the phenomenon approach them.
The effects can occur with a single streetlight or, as has been proven, with several lights at once. Less common is the occurrence of an entire row of streetlights gradually turning off as someone passes by, only to turn on as the individual moves away.

From time to time I cause that effect in the lights and I find it funny.
Perhaps many more people have a personal field that can produce these effects without knowing it.
