LED ghosting—where an LED bulb emits a faint, dim glow or intermittent flash even when the wall switch is turned off—is generally not considered a direct fire hazard under normal operating conditions. This harmless phenomenon occurs due to low-level capacitive coupling, induced voltage from parallel wiring runs sharing a conduit, or leakage current passing through lighted wall switches. While it indicates stray electrical energy, it does not create high-resistance arcing or excessive heat. You can troubleshoot ghosting easily by changing bulb types. You can verify that your corrective action is successful when installing bypass resistors, swapping to a different brand of LED bulb, or using a switch explicitly rated for no-neutral applications eliminates the residual glowing entirely without risking safety.
