    Solution: Reconnect the circuit and let the switch control the live wire.

    2: The switch has an indicator light or uses an electronic switch.

    Many switches have an indicator light inside, and if the indicator light is energized when the light is turned off, there will be current flowing through the lamp.

    Some luminaires use electronic lighting, such as infrared switches, voice-activated switches, and remote switches. These switches do not completely shut down the circuit. It will also cause the lamp to glow when the light is turned off.

    Solution: Remove the switch indicator or replace the mechanical switch.

    3: The wiring method of the dual control switch is wrong.

    There are many ways to wiring the dual switch, and if the electrician uses the following wiring method, it will turn off the light and glow.

    Solution: Rewire the lamp according to the zero line and control the live wire, as shown in Figure 4: the zero line is live.

    If the above problems are solved, the lamps will still be on after turning off the lights at night, and it is necessary to consider that the neutral line is live. Theoretically, as long as the switch is disconnected from the live wire, there will be no voltage above the zero line of the lamp, and the induced current cannot be formed. In real life, it is very common for the neutral line to be electrified.

    If the neutral line is not well grounded, the line is too long, the wire diameter is thin, or the neutral line current is too large, it will cause the neutral line to be electrified.

    The power supply is not completely turned off, or the neutral line is controlled.

    It's caused by induced electricity, so it doesn't matter.
