Why the red flashing LED indicator light sudden flash?

In daily life, indicators play a role of information interaction, generally through a variety of light color to express different signals. Flashing lights are flashing in the same color to convey information, complete information interaction. Like some stage lights, strobe lights, sound equipment and so on. The blinking time of the device can be set. At the same interval, the LED keeps blinking, which can also be called breath light, which is a common way of information interaction.

The reasons of sudden flashing can be classified into four categories.

1、Voltage instability
Normally, the light don’t flash when it is turned off. If it flickers, it could be due to an unstable voltage situation. In the use of lights, if the indoor capacity is relatively low, such as more electrical appliances, then it will cause voltage instability, may be turned off when the CFL flashing.

2、Power source 
If the socket is loose, so you need to take it off, and then plug it back in, so that will avoid flashing. In many cases, it’s all flickering due to loosing. After reprocessing again, it can be used directly, there will be no flashing situation.

3、The switch used to control lamp with indicator light
Because this “capacitive character” indicator light is constantly charged and discharged, bring about fluorescent lamp flashing, when it comes to this kind of situation, please remove switch and indicator light, it will be ok.

4、The switch is set on the zero line, caused by electrification of lamp body
Switch is set on zero line, the lamp body, switch and zero line become”capacitor”. Because this kind “capacitor” charge-discharge phenomenon, keep the fluorescent lamp flashing at night. In this case, change the zero and fire lines, just use the switch to control the live wire.
