In order to verify the hypothesis that under certain emotional conditions, the SLI endowed individual will cause the exhibition of the SLI phenomenon with greater frequency requires first obtaining a human subject who has or believes to have had past experiences of the SLI phenomenon.

Once a subject has been selected, the next step in isolating the experimental variables is to locate a public street light by which the subject has had or believes to have had previous SLI experiences (figure 1a). This acts as a control to some degree.

In the case of the subject chosen for this experiment, all of the lights by which he demonstrated the SLI phenomenon were mercury vapor lamps. Had this not been the case and had the subject been able to demonstrate the SLI phenomenon with other types of public lighting, it would still have been necessary to confine the experiement to a single lamp type.

It is also key that the lights be in a semi-isolated to fully-isolated location to ensure the absence of conflicting EMF generation and anomalies possibly resulting from light deflected from car headlights that could trigger the light sensors common to the types of street lights that are the focus of this experiment. Furthermore, it is necessary that the selected street lights are distant from other street lights to avoid similar deflection and to prevent interference with the Darkness Meter.

The Darkness Meter (figure 1c) is a device designed for this experiment. It consists of a calibrated optical sensor, clock, and spool-fed printer. The device is attached to the base of the lamp at the top of the lamp post. It is used to record instances of opperational oscillation both during the intervals when the Subject will pass beneath and all other times.

From five nearby lights selected by the Subject, only one med the necessary criteria (figure 1b).

After contacting the municipal utilities to verify that the chosen light had a recently replaced lamp and that there were no recent changes to the power grid in that aream the experiment could procede.

Essentially, the experiment consisted of regulated walks by the Subject around the preselected path by which he would pass beneath the selected street light several times in a given period. Between time periods, the Subject was exposed to specific forms of stimulation (figures 1d-1f) to alter the Subject's emotional state to sexual frustration, anxiety, melancholy, and anger in that order. This required four individual periods of walks for each day's experiment. This was repeated over a seven day trial period after which the Subject's long and the report from the Darkness Meter were examined for the emergence of patterns in the exhibition of opperation oscillation.
