led light goes on and off

Wondering why the LED light goes ON and OFF without proper reasoning?

It does not matter whether we are speaking of a LED light bulb or a strip, the causes for this problem share the same nature.

In this guide, we’ll cover every single possibility including the lights socket, the power income, the device’s functionality, and software adjustments.

When LED lights turn ON and OFF by themselves, users should first restart the device and inspect the power income as well as the source. The next step is to check for power fluctuations and in case the only device affected is the LED lights, perform a reset.

The solution includes addressing each possibility individually. This is why following the order of the solutions below is mandatory, in order for the guide to help.

Let’s jump right in!

Solution #1 Power Reset the Bulb

First, you should perform a power reset on your bulb, which is going to discharge the device, and make sure that there aren’t power problems with the bulb itself.

For this solution, you will need an object to step on and reach the bulb and its location. 

To power reset the bulb, unscrew it from the light socket and wait for 5 minutes!

Once that time has elapsed, re-attach the bulb back to its light socket and turn it on with the light switch.

Stand by for a couple of minutes (or for the time that it usually takes the bulb to go off) to check if the issue is fixed.

Alert: Make sure that the bulb is tightly screwed into the light socket.

Solution #2 Use a Different Socket

Chances are that there could be a problem with the light socket that you’ve installed the bulb in.

If that’s the case, you will often find the bulb going ON and OFF without anyone pressing the light switch. 

As the solution title suggests, you should install the bulb in a different light switch.

Follow these instructions to install your LED light in a different light switch:

  1. Once again, grab an object to help you unscrew the light bulb.
  2. Locate an alternative socket (it could be in the same room).
  3. Install the bulb in the new socket with a clockwise rotation.
  4. Trigger the power to the light socket using the switch.
  5. Stand by for a couple of minutes to check if the bulb will go OFF.
Note: Power fluctuations could be causing the light bulb to flicker!

Solution #3 Restart Room Power From Circuit Breaker

There could be a problem with the room’s power, making your bulb go OFF and ON.

Many users encountered this problem while using their LED light bulbs and it took them a while to realize that this issue envelopes all light sockets in the room. 

  • The electrical installation might be fluctuating!

Here’s how to restart your room’s power from the circuit breaker:

  1. Go over to your house’s circuit breaker.
  2. Open the panel and examine all switches.
  3. Look for a switch that has the light bulb’s room level.
  4. If the bulb is in the living room, for instance, turn off the power to the living room.
  5. Wait for 5 minutes while the power is turned off.
  6. Resume the power.
  7. Check if the bulb would still go on and off.
Tip: Disconnect other devices from the room’s electrical supply to relieve the installation.

Solution #4 Reset the LED Bulb

If nothing helped so far, then we suggest performing a reset on the faulty LED bulb.

This will flush the LED bulb software and restart the power which could potentially resolve the issue.

Here’s how to reset a LED light bulb in easy steps:

  1. Make sure that the bulb is screwed onto the socket.
  2. Head over to the light switch.
  3. Turn on the light switch for 3 seconds and then turn it off.
  4. Repeat the same process 3 x times.
  5. Wait for the bulb to reset.
Notice: The bulb will indicate a successful reset by pulsating slowly!

How to Fix When Strip Lights Turn On And Off By Themselves?

If you’re experiencing this problem with light strips, then we also have a solution for you. 

Unlike light bulbs, which are stand-alone devices, led lights are attached to a remote that controls their dim, power, brightness, color quality, and more.

If something with that power brick/remote goes wrong, it will most likely cause the bulb to flicker or turn ON and OFF.

Let’s begin with the troubleshooting of your LED light strip:

Fix #1 Power Cycle the Strip

By power cycling the LED light strip, you will discharge all of the electricity that has entered the device and could be causing the problem in your situation.

That’s why a power cycle is your best first move to resolving the problem with your LED light strip.

Here’s how to power cycle your LED lights in easy steps:

  1. Track the power cable of the LED light’s power brick.
  2. Switch the power button on the brick to “OFF”.
  3. Disconnect the power adapter of the brick from the source.
  4. Wait for 5 minutes while the power brick and LEDs discharge.
  5. Reconnect the power adapter of the brick back into the power source.
  6. Turn on the power to the LEDs with the power button.
  7. Check if the issue is now resolved.
Note: Keep the power brick disconnected for at least 5 minutes in order for the power cycle to be complete.

Fix #2 Use a Different Power Source

The next thing we could suggest is to plug your LED lights’ power brick into an alternative power source.

If there is a malfunction from the power source, you will often find your LED lights going ON and OFF, without proper reasoning.

Simply disconnect your brick’s power adapter and use an alternative wall outlet!

You should avoid connecting your LED lights to a power strip, especially if they are a powerful consumer (have a lot of devices in a single strip).

Once you’ve relocated the LED lights and connected them to a different source, check whether the issue persists.

Note: Test by plugging the LED strip into another room, hence, to a different power fuse!

Fix #3 Reset the Light Strip

The final thing you could attempt is to perform a reset on your LED lights strip

This will flush the software of the device and fix any glitches that could be making the lights go ON and OFF without any user interaction.

In addition, the reset is recommended to be performed once in a while to keep the LED lights working and refreshed.

Here’s how to perform a reset on your LED lights:

  1. On your brick, search for the small reset button on the side.
  2. Turn OFF the LED strip.
  3. Take out the power adapter.
  4. Press and hold the reset button.
  5. Plug the power adapter in.
  6. Let go of the reset button.
  7. Turn on the LED strip lights.
  8. Check if the issue is still there.

If the issue persists, consider purchasing a new power brick or delivering your current LED light strips setup to a technician for a checkup.

The repair might not be costly, but still, something in the device might be malfunctioning, hence, it’s not safe to be plugged in.

LED Lights Still Going ON and OFF by Themselves…

In case you’ve attempted everything from the guide above and nothing managed to help, the final step would be to reach out to the supplier.

It’s important to make sure that the problem is not on your side, and more accurately, not because of power fluctuations in your home!

Check whether your warranty is intact and call the LED lights supplier!

With a bit of luck, you’ll either receive a free repair or brand-new LED lights.

Quick Recap:

Thus, the LED light goes ON and OFF at random due to power fluctuations, issues with the light’s socket, or insufficient power source. We of course can’t exclude a problem with the lights so performing a factory reset should help us draw a conclusion.

Final Thoughts:

Now that we’ve learned why the LED light goes ON and OFF without any human interaction or proper reasoning, we are ready to troubleshoot the issue using the solutions above.

Keep in mind that you need to test the power installation with other light-emitting devices to determine where the problem is coming from and respond accurately.

Perhaps this is the time when you’ll actually put your warranty into use, so good luck!
