Streetlights That Go Out When You Pass: the SLIder Question

The claim sounds like a party trick until you meet someone who lives with it. They walk, a streetlight dies overhead. Another, next block. Their friends have stopped laughing because they've watched it for years: the lamp that quits as the car passes, the row that winks out along a jogging route. Such people call themselves SLIders — from Street Light Interference — and the community's roster includes the adjacent complaints: watches that die on their wrists, laptops that misbehave for them alone, card readers that fail at their touch and recover for the next customer.

What a sodium lamp does all by itself

The unglamorous star of this phenomenon is the aging streetlamp. High-pressure sodium lights at end of life enter "cycling": they heat up, overrun their voltage, shut down, cool, restart — for weeks. A cycling lamp goes out every few minutes REGARDLESS of who walks under it; a pedestrian is simply present for some cycles and, thanks to attention's bookkeeping, remembers exactly those. Add base rates (a long walk passes dozens of lamps; some failures are guaranteed), the invisibility of lamps that stayed ON, and the fact that you never see the lamp die when you're absent — and the SLIder experience assembles itself from ordinary maintenance backlogs. The watch-killers have a mundane cousin too: skin chemistry and habits genuinely do kill some watches faster.

What keeps the file interesting: the people for whom it clusters with STATE — outages tracking anger or distress, reported independently by families; the same specific lamp responding on repeated, witnessed passes while behaving for others (a testable claim — our favorite kind); and the poltergeist literature's old observation that disturbances center on one stressed individual. Formal lab attempts to catch human electromagnetic influence have caught essentially nothing, which the skeptics bank and the SLIders shrug at: it doesn't perform, they say. It happens.

Pick your lamp. Log your passes and a control's. Bring the ledger.
