LED lights off power or keep flashing how to fix?

When the LED light still flashes after the power is turned off, it is usually because there is a tiny current in the circuit. To solve this problem, follow these steps:

Check the zero live wire connection: First confirm that the switch correctly controls the live wire, not the zero wire. If the zero live wire is reversed, it needs to be rewired, ensuring that the live wire is connected to the switch and the neutral wire is directly to the lamp.

Remove the switch indicator: If the switch has an indicator, it may remain powered on when turned off, causing a weak current to flow through the LED. You can consider replacing the switch with no indicator light or removing the indicator light circuit.

Deal with poor contact: Check whether the switch and lamp wiring is firm, loose wiring may lead to small current leakage. Tighten wiring screws or replace damaged wires.

Eliminate induced current: If there are high-power appliances or dense wires near the lamp, induced current may cause flickering. You can try a contactor coil in series in front of the lamp to absorb these weak currents.

Replace the driver or luminaire: If the above methods are not effective, there may be a problem with the driver or LED component inside the luminaire. Consider replacing the entire luminaire or individual drives.

Professional electrician inspection: If you cannot solve the problem yourself, it is best to ask a professional electrician to check the circuit to ensure safety and accurately repair the problem.

With these steps, it is usually possible to solve the problem that the LED light still flashes after it is turned off. Safety first, before performing any circuit operation, make sure to disconnect the power supply and consider seeking professional help.
