Stopping LED ghosting—where an LED bulb emits a faint, dim glow or intermittent flash even when the wall switch is turned off—requires eliminating stray leakage current or capacitive coupling. This harmless phenomenon typically occurs when parallel wiring runs induce voltage or when lighted wall switches pass micro-currents. You can resolve ghosting by installing a bypass resistor (bleeder resistor) across the fixture terminals, swapping to a different brand of LED bulb, or upgrading to a switch rated explicitly for no-neutral applications. You can troubleshoot ghosting easily by changing bulb types. You can verify that your corrective action is successful when installing a bleeder resistor or compatible switch eliminates all residual glowing when turned off.
