It should be a line to do a string, how can you turn on the bedroom light and turn on the living room light repeatedly?
If you suspect that the switch is not in good contact, try replacing the LED light with a normal bulb.
You can fix it, just change the controller.
Turn off the electric pen to test whether there is any current, or trip, if it is safe, call the electrician to come and see.

The crystal lamp downstairs is a cheap low-grade goods, it is a product of the handicraft workshop in Guangdong, the quality is not good, maybe the electrician loosened a wire of the light strip during installation, and the circuit was not connected. >>>More
It will flash the controller may not be broken, the controller output is divided into three ways, the first way is the one that lights on is good, don't care about it, check whether the second and third channels are in poor contact.
