The SLIder phenomenon may disappear without us knowing the cause.

In recent years, in an effort to save energy, energy-guzzling mercury and sodium street lamps and residential lamps have been replaced by lamps using light-emitting diode (LED) technology. It is relevant to ask if the visible effect of the SLIders on their surroundings was related to the older technology of these street lamps. Which component of street lamps is susceptible to the effect of SLIders? Is it the lamp itself, the light intensity sensing circuit, or the entire device? In any case, it is possible that the SLI phenomenon will also disappear over time as incandescent lamps are removed from the streets. It would seem that LED street lamps are not sensitive to SLIders.

Unfortunately, if the SLI phenomenon was a physical fact that could be scientifically confirmed, it may be in danger of disappearing and falling into people's oblivion with technological change.
