Yilai Yuba has been on and off by itself.

It's poor contact caused by wiring problems.

Yuba consumes a lot of electricity and is prone to heat, which easily leads to poor lamp contact.

When the Yuba light flashes, we can check whether the circuit is damaged first. If there is a multimeter, we can first measure whether the voltage at the lamp mouth is normal, and then reconnect the circuit. If it can't be repaired, you can find professional maintenance personnel to repair it.
