Flickering Light Bulbs

Flickering lights can be extremely annoying, especially when you are trying hard to focus on that little chapter of your favorite book. It becomes hard to concentrate when the light bulb is acting funny on you. However, there exist simple and logical reasons behind the flickering of lights and the bulbs acting weird. It can be a simple problem caused by the fluctuation in voltage or can be a sign of some serious electrical problem. You need to understand the right cause for the flickering of your light bulb in order to deal with it. Let us see some causes of flickering light bulb problems and ways to fix them.

How to Fix a Flickering Light Bulb

Loose Connection
The most common cause of flickering bulbs is the loose connection between the bulbs and the sockets. Sometimes, due to several reasons, this loose connection can be broken for a moment, causing a flicker. Simple vibrations can cause disconnection of the wires that are not twisted properly and lead to flickering bulbs. This is a simple problem and can be fixed easily. Check if the light bulbs are loosely fit in the socket. Removing the bulb from the socket and refitting it tightly can solve the flickering problem in most cases.

Dead Bulb
If the problem of flickering bulbs persists even after tightening the connection, there must be something wrong with the bulb. A bulb usually flickers when it is about to burn out. Replacing the bulb with a new one can be the solution if the bulb has gone out completely. If the new light bulb flickers, the problem must be associated wit the cord or the socket.

Improper Wiring
Inspect the electrical cord and the plug carefully. Check the electrical wires attached to the outlets for any wearing off signs or frays. If you see any breaks or worn areas on the cord, it needs to be replaced. However, do not attempt to replace the cords on your own. Call for an electrician who is aware of the proper procedure and electrical safety precautions.

Faulty Socket or Outlet
Check if the socket or the electrical outlet is functioning properly. You could do this by plugging another appliance into the same outlet. If you find it faulty, get it fixed by an electrician. Also check the circuit properly. If it is overloaded, plug the light bulb in another outlet. If there are more than one light bulbs in the same light fixture, and the rest are working fine with only one bulb flickering, then the problem is most likely a defective socket or a faulty light bulb.

Contact Tab
Every socket has a piece of brass at the bottom, that makes contact with the base of the light bulb. Sometimes, if this brass piece is bent downwards, it fails to make proper contact with the bulb. Turn off the light switch and unplug the light bulb. Then, using a needle nose pliers, pull the brass piece slightly towards the top. Plug in the bulb and see if the problem is solved.

Electric Supply
A fluctuating or dim electricity supply may be the reason for flickering bulbs. If the bulb receives intermittent electrical supply, it is likely to flash on and off. Check if the other appliances are receiving full power, when the light bulbs flicker.

So, these were some common causes of flickering light bulbs and the ways to fix them. However, it would be best to call a qualified electrician to inspect your home for dangerous wiring problems.
