However, any blinks or flickers lasting longer than a few seconds each time should be reported to a qualified electrician, as this could mean that the circuit board needs replacing. For example, if flickering lights are infrequent and brief, this is usually not serious. Still, you should keep an eye on the situation, in case anything changes.

Who should I call for professional electrical services?

The UK National Grid delivers power to homes at around 230 volts per dwelling. Using the correct lightbulb type with the best light switches and dimmers should see an immediate improvement. The metal connections on the light switch may wear over time, or the one installed might be a defect and never had a properly made connection at all. Ask This Old House Master Electrician Heath Eastman demonstrates a variety of ways to troubleshoot and repair flickering lights.

Early intervention is your best bet here, especially if you're renovating a house or embarking on a similarly major project. Not all causes of flickering lights in the house are dangerous. They may be a simple fix you can undertake yourself (such as swapping bulbs) or a straightforward job for an electrician. Fluorescent or LED bulbs are sometimes interchanged with non-compatible dimmers, resulting in a persistent flicker. What's more, conventional dimmer switches tend to only accommodate incandescent or halogen bulbs, so make sure yours correspond accordingly to avoid any blinking or flickering.

The types of light bulbs you have may have to do with why they are flickering.

The licensed electricians at Dean’s Home Services are experienced with troubleshooting electrical issues in the Twin Cities. Given the potential health and safety risks involved with jobs like rewiring, electrics are a key area of concern for most homeowners. Heath demonstrated a variety of light switches and fixtures, which can be found at any home center.

Most likely the bulb itself is either faulty or not screwed or clipped in properly, so make sure you check this first. Want to know the reasons as to why your lights might be flickering? Flickering lights are a problem most households deal with at some point. This Old House Master Electrician Heath Eastman goes over a few common reasons why a light might be flickering and walks you through some basic troubleshooting.

Voltage Fluctuations in the Electrical System

The current travels through the wires until it reaches a socket, where it transfers to its final destination. If you have an outdated electrical wiring system with loose connections, there may be too much or too little resistance in the system, causing it to flicker. Aside from cases of loose electrical connections, flickering lights are rarely imminently dangerous, Duncan says.

“Valley parts of the city do see a longer kind of repair length,” Sangalang said. He also said that longer wait time is because light maintenance field staff come from BSL’s downtown office. About a third of the total repair incidents being requested involve copper wire theft. But in the San Fernando Valley, copper wire theft has grown to make up about 50% of total incidents being requested.

Reason #4: You Have LED Lights

If someone down the street is engaging in heavy electrical use, it can cause your lights to flicker. If this isn’t the case or if the lights are also flickering at their house, the issue might lie with your utility service. An electrician can determine if it’s time to call them for a repair.

Some 70 percent of home fires are caused by faulty wiring, according to the National Fire Protection Association. Needless to say, a flickering light bulb is not something that should be taken, well, lightly. Tripping circuit breakers, damage to the main breaker, and problems with power lines and transformers can also cause flickering lights.

There are many potential causes for flickering lights, which means you’ll have to troubleshoot the problem a little to find the cause. However, if the voltage goes higher or lower than expected, appliances can malfunction, and flickering lights are usually the first sign of this happening. You might notice the lights flickering in just a few areas of your house. If it’s the latter, go ahead and call an electrician right away.

Some Angelenos are staunchly against the possibility of lighting the sign due to these concerns. Learn the history to the future of street lighting in Los Angeles spanning from 1850 to 2025. Robert and his neighbor, Ginny Seiden, said they’ve repeatedly reported the outage to the city. Technically speaking, LED lights are more complex than old light sources. This is particularly important when you want to dim the brightness.

Homes with a standard 120-volt circuit should receive between 115 and 125 volts. If it’s over 125 volts, that can be the reason behind your flickering lights. This means that the electrical supply of your house is tied to the electricity usage of surrounding homes. So when a neighbor uses machinery or equipment with a heavy electrical load, it can cause the lights to flicker in your house. If you have a dimmer switch on the light, the cause of the flickering may be that you don’t have a dimmable bulb in the fixture. Try changing the lightbulb to a dimmable bulb to see if that fixes the issue.

Low voltage LED lamps require a stable and clean input voltage. The old halogen lamps did not have such high demands on the quality of transformer output. An unclean and fluctuating output voltage on the transformer can cause the LED lights to flicker. Yes, a poor connection with the electrical box can cause lights to flicker. If you have just one isolated light flickering in the house, there could be a problem with your bulb.

The sparks created by arcing can exceed 10,000 degrees Fahrenheit, creating a major fire hazard. If you suspect that damaged wiring is the culprit, cut off power to that wire by switching off the corresponding circuit breaker on your breaker box. Then pick up the phone and call a licensed electrician to assess and repair the problem. If the lights are flickering throughout your house, you could have a more serious issue with all of the wiring.

Some appliances, such as refrigerators and air conditioners, draw a large amount of electricity when they start running. This can cause a drop in voltage, which makes the light dim or flicker. Having those appliances on dedicated circuits can make the voltage fluctuations less noticeable. After switching to LEDs or when replacing a faulty LED lamp in some cases the LED light will start flickering. The intensity of the flicker effect may vary depending on the situation.
