Troubleshooting Outdoor LED Lights: Why They Come On and Off Randomly

2 Minutes Read

Outdoor LED lights are a fantastic addition to any home, enhancing its beauty and security. However, these lights can sometimes be frustrating when they start flickering, coming on and off unexpectedly. This can be annoying and a sign of an underlying issue that should be addressed promptly. In this blog post, we'll explore potential causes for your outdoor LED lights to behave this way and discuss the steps you can take to resolve the issue.


  1. Loose Connections


One of the most common reasons for outdoor LED lights to flicker or turn on and off is loose connections. The electrical connections at both the fixture and the switch can deteriorate over time due to exposure to the elements. Loose connections can cause an intermittent flow of electricity, leading to the erratic behavior of your lights.

Solution: Before calling an electrician, consider checking the connections yourself. Turn off the power to the lights, then carefully inspect the wiring at the fixture and switch. Tighten any loose connections and ensure no exposed or damaged wiring. If this solves the problem, you've saved yourself a service call.


  1. Overloading the Circuit


Another potential cause of your outdoor LED lights flickering or turning off is overloading the electrical circuit. LED lights are energy-efficient, but too many lights or other appliances connected to the same circuit can lead to voltage drops and erratic behavior.

Solution: Consider redistributing the load if you suspect your lights are on a circuit with other devices. You can connect your lights to a dedicated circuit, especially if you've added more lights over time. This can help stabilize the power supply and prevent flickering.


  1. Light Fixture Problems


Faulty light fixtures can also contribute to the issue. Outdoor LED lights are exposed to harsh weather conditions, and the housing can degrade, allowing moisture to seep in or causing a short circuit.

Solution: If you suspect the fixture is the problem, consider replacing it. Please ensure the new fixture is rated for outdoor use and properly sealed to protect against moisture. This step might solve the issue, and it's a relatively simple DIY project.


  1. Voltage Fluctuations


Voltage fluctuations in your home's electrical supply can cause outdoor LED lights to behave erratically. These fluctuations might be due to problems with the power grid or voltage surges from other appliances.


Solution: Consider installing a voltage stabilizer or surge protector to protect your outdoor lights from voltage fluctuations. These devices can help regulate the power supply and prevent lights from flickering or turning off unexpectedly.


  1. Contacting a Licensed Electrician


If you've tried the above steps and your outdoor LED lights are still causing problems, it's time to contact a licensed electrician. A professional electrician can thoroughly inspect your outdoor lighting system, including the wiring, connections, and circuit, and identify any underlying issues requiring specialized repair.


Still Have Questions? Talk To An Electrician.


It can be frustrating when outdoor LED lights come on and then go off intermittently, but it's essential to address the issue promptly.

In many cases, simple DIY solutions like checking connections, redistributing the load on your circuit, or replacing a faulty fixture can resolve the problem. However, if these measures don't work, don't hesitate to call a licensed electrician.

They can identify and fix any complex electrical issues that might be causing your outdoor lights to misbehave, ensuring your home remains well-lit and secure.
