Why are all my house lights flickering?
Random light flickering often starts mildly when appliances run, but can escalate into severe flashing across multiple rooms even when everything in the house is turned off. In other cases, lights in newer homes suddenly start blinking in repetitive patterns simultaneously, ruling out simple explanations like bad individual bulbs.
