After the intelligent switch turns off the light, the light band is slightly brighter.

1. Reverse connection of live wire and neutral wire;

2. Use touch switch or induction switch with indicator light;

3. Incorrect wiring method leads to induced electricity.

The reversal of the zero-fire line of the switch will produce dim light,

Even if the double wire of the lamp holder is connected to the fire line, it sometimes gives off a weak light.

The switch, lamp holder, dirty or moldy in rainy days, and the zero fire of junction box switch are too close, which will all produce induced current and lead to dim light.
