Why Is My Light Bulb Flashing When It’s Off

Why Is My Light Bulb Flashing When It’s Off? This Is Why! 

Some led light bulbs flicker, and flash light when switched off. The LED light bulb is widely used since it has a great advantage concerning color index and energy savings; however, it flickers when turned off. This can be annoying due to some technical disadvantage that occurs when you use the lightbulb for many hours. However, you need not worry as you can solve this problem easily by following quick tips. 

Why is my light bulb flashing when it’s off? Your light bulb flashes light even after being switched off due to a small electric current flowing through the light bulb. This makes the lightbulb unsuccessfully try switching on again.

Different Reasons Why My Lightbulb Flickers Or Flashes Light When It’s Off

  • There is some lightning technology that is more prone to flashing off the light when switched off. This is common in fluorescent light bulbs and led lights due to improper connection to the dimming system or driver and when you connect bulbs to failing ballast. This may not be a serious issue; however, you can replace the lightbulbs if this flashing-off light makes you feel annoyed. 
  • If you screw the bulb loosely in its socket, it can flicker after switching it off. Turn the bulb off, wear heavy-duty glove before tightening and grasping the bulb. If you see a light bulb flashing even after this, then the issue lies somewhere else
  • Another cause for flashing light when your bulb is switched off is corrugated pipes. A big problem can be caused when cables are held tightly together. It will result in weak electronic interference or disturbance. Therefore, if you detect that the light bulb flickers due to this issue, put a good amount of distance between corrugated electrical cables. 
  • Another reason for your bulb to flash light even when switched off is the bulb society’s wrong insulation on the bulb holder. When the switch stops the neutral but not the phase, leakages are caused by the latter and keep the bulb on. To solve this problem, you should apply residual electrical current device. 
  • If your light switch isn’t connected with the lightbulb, the faulty switch can cause your bulb to flicker even after being switched off. Toggle the light switch by turning it on, then off, and then again on. You can also replace the light switch
  • It is a serious concern if there’s loose electrical wiring which may cause your bulb to flash light and lead to a house fire. Shut the light off at the circuit breaker before removing a fixture to check your electrical wiring. If your light bulb still flashes light after being turned off, call for an electrician to evaluate your house’s electrical wiring to be on the safe side and avoid risk. If you find the fixture insecure or loose, call a professional electrician quickly. 
  • A lightbulb can flash light when switched off because of the return of possible current from power supplies, drivers, and transformers in the bulb system.

How To Solve The Problem Of Lightbulb Flickering? 

In general, this kind of flashing problem occurs when your bulb is switched off, and when the bulb is switched on, they again work normally. When you switch off the bulb, these lights flash specifically if the surrounding area is dark. The lightbulb will remain lit with few flashes, or the bulb flashes light. 

  • The first rule to solve this issue with your bulb is to determine the source of the problem. You can get rid of this issue if you go back to where the problem is typically coming from. This flickering problem normally starts from your power supply, and current flows via the bulb holder before reaching your lightbulb. You need to ensure that your power supply of the lightbulb is interrupted correctly in the phase. 
  • If the phase gets interrupted, but the flashing and flickering continues, you should ensure that the inverter or diverter and the switch are connected properly to the phase. 
  • If there’s a problem with the power supply, you need to reconnect wires separately to offer the correct power supply. When you press a switch, then different wires should be used for the power supply, thereby avoiding the usage of the same electrical wires. 
  • Lost or loose light plug is an issue with your bulb that makes it flashes after switching it off. This can be due to a loose connection between a plug and an outlet. Ensure to check the plug and see if it’s attached to a wall socket. Try to unplug, adjust metal prongs, and plug it in again.
  • If other electrical components continue to work normally while your bulb flashes light after switching it off, it’s because of a loose connection with the socket as it has been used for a long time. Try to tighten it or replace your bulb.

What Are The Varieties In Nature Of Lightbulb Flickering?

The different reasons stated above regarding light flashing, when turned off, is electrical. However, your bulb can flash light due to chemical or physical reasons. For instance, a few bulbs are manufactured with the help of phosphorus, which is an element associated with highlighting the brilliance and luminescence of the lightbulb.

Light photons charge the phosphorus, retain the light charges for some minutes, and continue emitting a beam of light when you turn the LED bulb off. This light beam doesn’t relate to common flickering and corresponds to constant, non-long-lasting, and weak light.

Therefore, before considering the bulb to be defective and going for replacement of your light bulb, you must check all components and ensure that they are connected rightly and check the condition of diverts, switches, buttons, and the bulb holder.

Do I Need To Call For An Electrician If My Bulb Flashes Light Even When Switched Off?

When you switch on an electric appliance with high wattage and see the light bulb flicker, this is a voltage fluctuation issue. Purchase a voltmeter to check the voltage fluctuation. If the bulb is flashing light due to this electrical issue, you need to call an electrician. You can buy a 130-volt bulb that can tackle higher voltages easily. 

Conclusion

It’s not a great idea to ignore an electrical or lighting issue. If you see your bulb flash even after switching off, investigate and find the underlying problems. If the issue persists, then call for an electrician.
