I have received several stories like the one above from readers. It doesn't happen every time with every streetlight, but it occurs often enough to make these people suspect that something unusual is going on. Very often, SLIders also report that they tend to have an odd effect on other electronic devices. Lightbulbs constantly blow when the SLIder tries to turn them off or on. Volume levels change on TVs, radios, and CD players.
Watches stop working.
Children's electronic toys start by themselves when the SLIder is present. Credit cards and other magnetically encoded cards are damaged or erased when in their possession. Any attempt to pinpoint a cause for SLI at this point would be mere speculation without a thorough scientific investigation. The problem with such investigations, as with many forms of psychic phenomena, is that they are very difficult to reproduce in a laboratory. They seem to happen spontaneously without the deliberate intention of the SLIder.
