The switch wire may be connected to the zero line, but if it is connected to the live wire, it should not be.
The two wires of the lamp were cut and connected, and the principle was very simple.
The switch of this lamp is disconnected from the neutral wire, there is always the electricity of the live wire in the lamp head, and the induced electricity gathers to a certain extent, and it discharges once, that is, the lamp flashes once, and the solution is to switch the neutral wire and the live wire, I hope it can help you.
What do you mean by one or two? The lamp is called one or two, if the lamp will flash after turning off, it means that it is an energy-saving lamp, in this case, the switch of the lamp controls the zero line, and the live wire is not disconnected by the switch directly to the lamp head, resulting in the lamp head has been electrified.
If this situation occurs when the power is on and the light is on, check the line, and there may be a problem of poor contact; If it flashes without power, replace the wires that enter the switch - make sure the switch is fire-off!
