Flickering Lights: Loose Wire or Punctual Ghost?

Flicker is the haunted house's official language — every film says so — which is a pity, because flicker is also the electrical system's language, and some of its sentences are urgent. Our files are full of both: the bulb that stutters every night at nine (the neighbour's dryer, it turned out, on a shared transformer), and the hallway light that dims — witnesses swear — WHEN THE DEAD ARE DISCUSSED, a timing trick it performed at the wake, twice at anniversaries, and never for the electrician.

Read the flicker like an electrician first

The diagnostic ladder, worth knowing for safety alone: ONE lamp flickering = bulb (dying LED drivers flicker theatrically), loose bulb, worn switch, or lamp cord. One CIRCUIT = loose neutral or connection at a fixture or junction — genuine fire-risk territory, take seriously. WHOLE HOUSE dips = big loads starting (HVAC, dryer, well pump — yours or a close neighbour's) or, worse, a failing service neutral: dimming AND brightening in different rooms simultaneously is a call-the-utility-today symptom. Old aluminum wiring, corroded panels and DIY junctions supply the rest. LEDs add their own gremlins — incompatible dimmers make them pulse like séance equipment. An electrician's hour resolves the overwhelming majority of "light ghosts", and occasionally prevents the literal kind of house-fire our archive never wants to host.

What the ladder can't diagnose is CONVERSATION. The residue cases run on timing and address: the light that answers questions — flicker once for yes — tested cold by skeptical relatives; the single bulb over HER chair, misbehaving only on her dates, across bulb replacements and fixture swaps; the whole-room dip at the moment of a distant death, logged before the phone rang. Electricity explains flicker completely. It keeps no calendar. Fix the neutral. Then tell us about the bulb that knew the date.
