This page may need to be Street light interference, or SLI, is a claimed phenomenon where people inadvertantly trip the daylight sensors on daylight-sensing light fixtures. Critics usually attribute the phenomenon to two things. First, the lights are simply shutting off for explainable reasons- for example, sodium vapor type lamps will blink on and off when they start to fail, as they have experience voltage spikes. Second, due to observer bias, the SLIder notices the light turning off (or on), while they pay no attention to lights that are operating normally. SLIders have attempted to rebuke these through demonstration; however, as yet, no one has been able to cause interference during a demonstration.
