Why Do My Led Lights Turn On By Themselves?

LED bulbs must be handled carefully because they are delicate electrical fixtures. Below are a few causes for the LED lamp to switch ON and OFF.

Any interruption in power to the associated circuits might have an immediate impact on LED lights. The LED lamp may turn off if a refrigerator is connected to the same course and its compressor activates, drawing more power. Once the power distribution has been normalized, it will return.

What Causes LED Lights to Turn On By Themselves

1. Changes in Power

A few led lights typically switch on by themselves to indicate that there has been a power outage and that there is no power to let others know.

Even when the lights are off but attached to a live power source, this still occurs in some instances.

Following a power loss, it is typical for some LED lights to come on by themselves and stay on until the light switch is shut off again.

However, it could be a sign of a power fluctuation if the lights turn on themselves despite no power outage or maintenance taking place.

Power fluctuations might be brought on by difficulties with the breaker or wiring in your home’s electrical system.

An electrical issue may be present if you find that your led lights frequently come on by themselves. Your home’s electrical system must be inspected in this situation, so contact an electrician.

2. Affecting Other Infrared Devices


Typically, infrared-based led lights behave in this way. The electromagnetic radiation known as infrared can cause interference with other nearby infrared equipment.

Your led strip lights lighting on by themselves may be caused by other infrared devices that are close by. The most typical example is a television remote, as some of its buttons occasionally also work to turn on LED lights.

An infrared controller for led lights can be negatively impacted by the infrared light that a remote control emits. Other times, the infrared controller sends out a light signal that could clash with other lights in your house.

The self-illuminating led lights in this situation might not need to be replaced. You might buy an infrared repeater or use the remote control to switch channels and control the lights.

3. Factory Error or Minor Faults

Led strip lights with a bad controller or broken components behave this way.If your led strip lights switch on by themselves, there may be a problem with the wiring or the components. Since fixing the controller or swapping out the broken components might be too expensive in this situation, changing the LED strip lights is your best alternative.

You should be aware that even if there is nothing wrong with your LED lights, they may still turn on by themselves. You can check your product’s troubleshooting center to discover how to fix the problem if this is the situation. You may usually fix the issue by turning your led lights on and off again. And in other situations, you might need to reset your gadget.

4. The Energy Source Is Inefficient

A defective power source is occasionally to blame for led strip lights not turning on properly. The lights may switch on by themselves if your power supply is malfunctioning.

Many factors, including the following, may cause this to occur:

  • It’s essential to correctly plug in the power supply.
  • Check that the batteries have been configured correctly and are wholly charged if your lights are powered by batteries.
  • If your light is fueled by a power source, be sure there is adequate output to power all of the lights.
  • Check to determine if each strip has a different input voltage if you have many strips powered by the same power source.
  • Check whether the light’s power source’s fuse hasn’t blown.
  • A switch with additional wattage needs to be installed instead of your current one if your light is controlled by a dimmer.
  • The led light might turn on if you have a live wire that constantly powers your lights, but it frequently trips.
  • A circuit breaker may have blown in some instances. Before calling an electrician, check these first to see if they are the problem.

The light bulbs may need to be changed if your power source is functioning correctly, but your lights still won’t turn on or do so on their own.

5. Availability Sensors

Your lights turning on by themselves could be happening for a variety of reasons. Another possibility is that they react to an outside stimulus, such as occupancy sensors.

Devices called occupancy sensors to keep an area under surveillance for activity. They come in both passive and active infrared varieties (like motion detectors). The lights will come on once occupancy has been determined.

To automatically manage a structure’s interior and exterior lights, these sensors can be installed throughout the lighting system. Make sure the occupancy sensors are not pointing towards one another if you have them.

Also, remember that specific systems will place a sensor on each light; therefore, ensure that these are not pointed at other lights.

You might want to replace your occupancy sensors with a new type of sensor or have them calibrated if you have occupancy sensors. However, your lights switch automatically when there are no occupancy sensors.

6. An older power supply or transformer than five years

Having a power supply that is more than five years old may be one of the causes of your led lights coming on by themselves. Replace any power supplies over five years old because this indicates that they are more likely to fail.

Check to see if the plugs are secure and if you have a more recent power supply that isn’t more than five years old. Additionally, look for any loose wires or evidence of heat damage.

Consult an electrician if there are no symptoms of overheating. Still, the power source has recently been changed because this could be a hint of a more significant issue.

7. Some LED Strip Lights Can Be Set To

Your lights may be on because they were set up to turn on at specific times throughout the day. These functions are frequently included in LED strip lights, so they switch on following the time of day. This indicates that these lights contain sensors that enable them to turn on when it becomes dark and switch off when there’s power.

This is most likely the cause if your lights are on even when they are not switched on. You may do a quick test by turning them off and timing how long they remain on. If the interval at which they automatically switch on is regular, the light has either been configured to do so or is set to do so by default.

Typically, a portable remote control or an infrared receiver is used for programming. A fault may cause the led strip lights to turn on themselves if these aren’t functioning.

Take the following actions to prevent this from happening:

  • If your lamp has a timer function, it should say so in the handbook, which should also have instructions on how to adjust its settings (if it does, then go ahead and disable any timers).
  • You can disable the automatic off feature that turns your light off after an hour of use if it doesn’t include a timer function:
  • If your light has a “reset” button, locate it in the user handbook and push it to return the lights to their factory settings.
  • Check your work notes from when you first installed the strip light because you will now need to reenter any settings you have previously programmed into.
  • Try resetting the lights by trial and error if you’ve misplaced your notes.

8. Failing Led Strip Light Controller

Why Do My LED Lights Change Colors By Themselves?

Another potential cause of your led lights turning on by themselves is a broken controller or remote. Make sure your controller is in working order if you use it to switch on or off your led strip lights. Change your remote control if you see that the controller is broken or hasn’t been working for a while.

A different controller should be used for each light if you have several lights. This will make it more difficult for the other controllers to switch them on or off. If your controller is in go, but the lights switch on by themselves, it might be time to get a new set.

How to Stop LED Strip Lights from Auto-Oning

There are a few ways to stop your led strip lights from coming on by themselves, as I’ve already alluded to. You can avoid this by doing the different things on the list below.

  • The power supply should be checked first to ensure it isn’t malfunctioning if your led strip lights start up at strange times.
  • The controller must be changed if you’ve done all of this and your lights are still coming on randomly.
  • Your led strip lights won’t be on for too long, thanks to the built-in timer in newer controllers.
  • Any controllers that are not operating correctly can be disposed of and changed for new ones. This will assist in preventing the midnight activation of your led lights.
  • To ensure your occupancy sensors are operating properly and not creating any issues, maintain them regularly.
  • If you leave the room or get into bed, always turn off your LED lights.
  • If your hallway has a control panel, be careful to turn it off at night and turn it off when the place is unoccupied.
  • Learn how to configure your LED lights so you may change their behavior to fit your needs.
  • Check to see whether the power supply isn’t being overloaded.
  • You can ensure that each light is switched on or off properly if you utilize a different control panel for each one, if at all possible.
  • If you want to control a total of two lights with each controller, use different controllers for each room.
  • Set up your LED lights when you initially get them and write down the configurations for later use.
  • You may also keep a record of the settings you modify after installing your led strip lights so that you will remember what to do if they suddenly start coming on by themselves.
  • Reset your lights to factory defaults if things start to become confusing.

It’s time to replace your led lights if, after doing everything, your lights are still coming on automatically.
