There are a variety of lights and decorative items for Christmas, and these do not have fixed settingsYou have the flexibility of customizing them too. 

Stop Christmas Lights from Blinking 

There are some kinds of light flash because they have special bulbs that twinkle constantly. Others might be flashing if they are not getting proper voltage or power supply. This can be when lights are flashing partially. 

  • Look for some clear bulbs with red or silver strips, these are usually twinkle bulbs and they transform a normal strand of lights into blinking ones.
  • You can replace them with normal bulbs to see if they are still blinking, or not? The areas surrounding the bulbs you just replaced should not blink.
  • Now, you can also switch to a completely different strand of lights that do not have that twinkle feature. Many times you have a dial that can turn this feature on and off, and this is simple but also easy to miss.
  • When you are purchasing the light strands, take note if they come with blinking feature that cannot be turned off manually, in which case, nothing can be done afterwards. 

Keep Christmas Lights from Flashing 

Sometimes, you do not have any flickering or twinkling feature, but the lights are just dimming and shining because of flicker due to electricity. There can be a voltage problem with your power socket, the adapter of the strand of lights you purchased or something else.


  • Loose wiring is the most widely found reason for flickering Christmas lights and is also the main cause of house fires, so be careful. 

  • Try shutting the light off at the circuit breaker and double-check the wiring, do what you know and contact the electrician if required. 

  • If there is an LED light strand, then you can look for the dimmer switch or try replacing one or two LEDs that are flickering or blinking. Sometimes, simply tightening the contacts of the bulb can self correct this unusual blinking. 

  • At times, just replacing one or two of the LEDs with the traditional incandescent or energy-saving bulbs also does the trick, and it is simply because of the load issues. 

Stop White Christmas Lights from Flashing 

If you have purchased the bulbs that twinkle, blink and flash as a feature that you were not aware of when buying, there are some changes that you can attempt, but without any security. There are a few ways you can try to remove the twinkling feature even if they did not come with those control boxes that would have made that task simple and straightforward. 

  • First, you have to know that you need to do some replacement to the bulbs, LEDs as well, and therefore you have to look for tags that tell you the voltage for each of the bulbs in your light strand. 
  • Usually, you can find them to be around 2.5V for each small single bulb, and once you have found the voltage information, you can go to your shop to get some replacements that do not blink. 

  • Now, some strands have partially some bulbs that blink, while others don’t. In this case, you can locate the ones that are blinking, and try to replace them. 
  • These are usually marked with some color for identification. After turning off the power, remove the bulb nicely.  

  • Replace it with a non-blinking one, fold the wires back into the casing nicely. When done, reinsert the new bulb, and the casing back into the base. 


  • Ensure proper safety before removing or replacing bulbs, and unplug them before working with electricity. 
  • When working with electricity, make sure to read the voltage information and other specifications on the tags or cover of your light strands.

How do I stop my Christmas lights from flashing?

Look under the tag on the strand of lights to find voltage information. Locate the blinking bulbs. Some light strands blink because they have special bulbs that twinkle. If that’s the case with your lights, you can get rid of the twinkle feature by switching out the bulbs.

Why are my Christmas lights flickering?

Your Christmas lights flicker because they aren’t traditional incandescent lights that create lights based on heating a small wire element in the presence of an inert gas inside the little glass bulbs. This is what creates a flickering, choppy light result especially when the light string is moving.

How do you make Christmas lights twinkle instead of blinking?

Short answer. Yes, just replace one of the bulbs in your Christmas light string with a red-tipped bulb and that section of circuit will flash on and off!

How do you turn off twinkle lights?

First, unplug the lights. Then, for each blinking bulb, hold the bulb by the base (where the light attaches to the strand) and pull out the bulb and the bottom casing. Remove the bulbs from the casing.

Why do my LED lights keep flashing?

LED bulb flickering can be traced in almost every instance to a non-compatible dimmer switch in the lighting circuit. LED bulbs don’t have glowing filaments. When the dimmer switch goes off and on many times per second, the LED bulb becomes a flickering strobe light.

Why won’t my LED lights stop flashing?

Well, it’s because the LED power supply has something called ‘overload protection’. The power supply turns on, realises it is overloaded and then cuts out using the overload protection. It then turns on again and does the same thing – unless you reduce the wattage that the LED strips are drawing from the ouput.

How do I fix flickering lights?

If your light bulbs are flickering, turn off the power and, using a glove to protect your hand from heat, screw the bulb in tighter. Loose light bulbs mean the socket isn’t making proper contact with the bulb, and that can cause intermittent flickering. Even recessed lights can loosen, so check those connections first.

Do LED lights flicker when burning out?

LEDs only provide light when an electrical voltage runs through them. If this voltage is not constant, flickering will happen. This only affects LED bulbs because others like halogens and incandescent maintain enough heat to cover brief gaps in voltage. LEDs don’t.

How can I make my lights flicker?

Are flickering LED lights dangerous?

Lights can flicker for a number of reasons, some of which are harmless and others hazardous. Light dimmers with incompatible lightbulbs (such as LEDs) can flicker when they’re set on low. Fortunately, this is not a dangerous situation either, however annoying it may be.

Should I worry if my lights flicker?

Flickering Lights are a frequent cause of concern. You probably don’t need to worry about lights flickering and dimming in the house if: Your lightbulbs are incompatible with your dimmers. For instance, flickering LED lights when they’re on a low setting can be annoying but they’re not dangerous.

What are flickering lights a sign of?

But sometimes, a flickering bulb is a sign that the light fixture is damaged or the electrical connection is faulty. Do not ignore these signs! Turn off the power immediately and check the connection to the fixture and its internal wiring. If you are not confident in your abilities, call an electrician.

Why do my dimmable LED lights flicker?

The main cause of flickering with dimmable LED light can usually be traced back to the dimmer switch. Dimmer switches come with a minimum compatible load (in short, the amount of Watts it can process). That’s why it’s important that you get a compatible LED dimmer switch to avoid any potential flickering.

What is the best dimmer switch for LED lights?

What would cause lights to flicker and dim in a home?

If multiple lights flicker, this may mean you have loose service conductors in your main electrical panel or meter base. Other causes of flickering lights that call for professional attention include faulty connectors, corroded wiring or a mixture of copper and aluminum wires that haven’t been properly connected.
