There are several reasons why LED lights keep flashing: First, it is caused by poor contact of external power supply lines; Second, the LED driving power supply that supplies power to the LED light source is faulty, and the output DC contains AC components (that is, insufficient rectification or unstable current has interference); The third is the mismatch between power supply and LED light source. Generally, the second one is more likely.
