You can open it to see if the line is broken.
Go to the place where the bulb is repaired and let the master show you if the thread inside is broken, and if it doesn't work, you can buy a new one, and it will affect you to sleep at night.
It may be that there is a problem with the lamp holder and the contact is poor. That's the way it is in my house, the light bulb comes back on when it is reinstalled. >>>More
Dead, need a new light to succeed him.
Don't turn it on first, disassemble it in a ventilated place, or in a rice tank, or dry it with a cool breeze on a hair dryer, and then turn it on.
If you fall once, first observe the appearance, if it is not broken, then see if it can still walk normally.
