Why do my lights flicker

Flickering lights are trademarks to horror and suspense films. It is also a mark that there might be something wrong with it. Flickering lights sometimes occurs when the bulbs are connected to a failing ballast or in fluorescent lights within the first minute or so of turning them on as the phosphors reach illumination. LED lights may also flicker when improperly connected to a driver or with a certain dimming systems. Usually it doesn’t indicate a serious electrical issue, but you may want to consider replacing your lights if the flickering gets too often and eventually gets annoying.

Check Light Bulb

So your lights flicker, obviously it’s not good. You turn off the switch and removed the bulb then fiddled with it for a while and screwed it back in. When you turn your lights on the flickering disappeared. Voila! You fixed it! Flickering lights can actually be caused by something as simple as the bulb not being screwed in properly. Some people might be too lazy to check the bulb itself since it may be covered with some light fixtures. Simple isolation might just fix the problem, however, even though you made sure that it’s screwed in correctly and the light still flickers, then the issue is not the bulb.

Toggle type light switch

Check Light Switch

One of the culprits why your light could be flickering might not be on the bulb itself but on the light switch itself. Try isolating the issue by toggling the light switch on and off or shutting your lights off for a while then turn it back on. If the procedure rectifies the issue that should be good, however, if you need to constantly need to do this to keep your lights from flickering, it would be highly suggested to replace your light switch.

Check flicker timing

Pay attention, if your light flicker when you turn on an appliance with a high wattage (fridges, air conditioners, motors and power tools, heaters, etc), then the reason could be that the voltage in your home is fluctuating too much. The power setup in your home may not be equipped enough to handle too many appliance running all at once. This kind of issue is not easy to resolve and  you should never resort to D-I-Y solutions. You will have to contact a professional and licensed electrician to rewire your homes electrical circuit to set it up according to your homes electrical needs.

Electrical Wirings

Check Electrical Wiring

You’re done checking the light bulb, you have isolated the light switch as well as checking if your light flickers when you turn other appliances on. One area you would also need to look at is the wiring towards the lights and switches. This would be easy if you know how to remove light fixtures to check underwires but if you’re unsure, it would be better not to touch it and contact a licensed electrician. Loose wiring is the most serious reason for flickering lights and main cause of fires.

As they say big things come from small beginnings, so while the issue is minimal at flickering lights be sure to have it checked by a licensed electrician. It’s never a good idea to ignore minor issues especially when you’re dealing with electricity. A licensed electrician will be checking your homes electrical wiring.  A surge protector might be a good idea to double up your homes safety measures.
