What's the matter with the lights off and the light dim? Not before.

1, if every light in your house is like this, it may be that the live wire and the zero wire are connected backwards in the open space at home. So it is usually left-handed and right-handed. If it is connected in the open position, it may leak electricity, so the light bulb will be slightly brighter after turning off the lights. This is very dangerous. It is recommended to find a property manager or an electrician switch.

2. If there is only one switch-controlled lamp, it may be that the switch wiring of this lamp controls the zero line, so there will be a problem that the lamp will have a certain brightness. At this time, it is necessary to remove the light, change the control line and connect the switch to the live wire instead.
