How to Stop Led Shop Lights from Interfering with Radio

Don’t worry – in this blog post; we’ll be looking at how to stop led shop lights from interfering with radio so that you can enjoy uninterrupted music and conversations without the background buzz! Keep reading to learn more!

Why Does My Led Light Bar Interfere with My Radio?

The most common cause of radio interference from LED light bars is electrical noise. LEDs generate a lot of electrical frequency noise, which can interfere with low-frequency signals such as those used by AM/FM radios. This type of interference is known as electromagnetic interference (EMI).

To prevent EMI interference with your radio, the first step is to make sure that your LED light bar is properly installed. Make sure the wiring is secure and free from any contact with other metallic surfaces, as this could be a source of interference.

Additionally, try to keep the light bar away from sensitive components such as antennas or amplifiers. It’s also recommended to insulate the light bar with ferrite beads, which will help reduce EMI.

If the installation is properly done and the interference persists, then you may want to consider using a noise filter or signal booster for your radio. These devices can help block out electrical noise and allow your radio signal to come through clearly without any interference.

There are several different types of filters and boosters available on the market, so make sure you do your research and find one that is compatible with your radio.

10 Methods How to Stop Led Shop Lights from Interfering with Radio

1. Use a Radio Frequency Filter

One way to stop LED shop lights from interfering with radio frequencies is to use a radio frequency filter. This type of filter is designed to block out interference from LED lights, and it can be attached directly to the light fixture.

Use a Radio Frequency Filter

This is a simple and inexpensive solution that can be used in any shop environment. If your shop is in an area where LED lights are causing a lot of interference, this filter may be necessary to prevent disruption.

2. Move the Light Fixture Away from the Radio

Another way to reduce interference is to simply move the light fixture away from the radio. If possible, try to keep the light at least 3 feet away from the radio. This will help to reduce the amount of interference that is caused by the light. Additionally, if you have multiple lights in a room, try to keep them from being too close together. This will reduce the amount of interference that is caused by each individual light.

3. Use a Lower Wattage Bulb

If you are using an LED bulb that is high wattage, it can cause more interference than a lower-wattage bulb. Try switching to a lower-wattage bulb and see if that reduces the interference.

You may also want to try changing the type of LED bulb you are using. Different types of LED bulbs can produce different levels of interference. If your shop light is in a confined space, you may want to switch to an LED with a soft white color temperature. This will help to reduce the amount of interference your shop light produces.

4. Use a Different Type of Light Bulb

In some cases, simply using a different type of light bulb can reduce or eliminate interference. For example, halogen bulbs produce much less electromagnetic interference than LED bulbs. If your shop lights use LED bulbs, consider replacing them with halogen or fluorescent bulbs.

Halogen Bulbs Produce Much Less 

However, be sure to read the manufacturer’s instructions carefully before attempting to replace the bulbs.5. Install a FilterIf you still experience interference after trying the other steps, installing an RF filter may solve the problem. An RF filter is an electronic device that prevents radio frequencies from leaking out of the light fixture and interfering with other devices.

5. Add Shielding to the Light Fixture

If you are still having problems with interference, you may need to add shielding to the light fixture itself. This can be done by wrapping aluminum foil around the fixture or by using a commercially available shielding kit. This should block any electromagnetic radiation that is being emitted by the lights.

If you do this, make sure to also ground the shield so that any interference that gets through is safely dissipated. If you’re not sure how to do this, it may be best to consult a professional electrician. With the right shielding, you can be sure that your radio reception is not being interfered with.

6. Move the Radio Away from the Light Fixture

Just as you can move the light fixture away from the radio, you can also move the radio away from the light fixture. Again, try to keep at least 3 feet between the two devices. If possible, try to move the radio away from any other electronic devices that may be nearby.

This will help minimize interference and maximize your ability to hear clearly without static. Additionally, it’s best to keep the radio away from any large metal objects, such as filing cabinets or tables, that may be nearby.

7. Use a Radio with Built-in Shielding

Some radios come with built-in shielding that can help to reduce or eliminate interference from LED lights. If you are in the market for a new radio, look for one that has this feature.

This can be a great way to reduce interference without having to take other steps. If you already have a radio, consider buying an additional one with built-in shielding for the times when you need it. Make sure that the shielding is sufficient for your needs before purchasing.

8. Use an External Antenna

If your radio has an external antenna, make sure that it is as far away from the light fixture as possible. In some cases, moving the antenna just a few feet can make a big difference in reducing interference.

If you’re using a wireless antenna, make sure that it is properly connected and that the connections are secure. If your radio has an internal antenna, you may need to purchase an external antenna in order to get better results.

9. Turn Off the Light When Not in Use

If you are not using the LED light, simply turn it off until you need it again. This will eliminate any possibility of interference while also saving energy. It is best to turn off the LED light when you are not using it at all or when you have no need for additional light. While LED lights are more efficient than other types of lighting, they still consume energy when left on.

10. Use a Dimmer Switch

Installing a dimmer switch on your LED lights can help to reduce interference by reducing the amount of power that is going to the bulbs. This is an easy way to reduce interference and can also help you save energy.

You can also find dimmer switches that are specifically designed to reduce interference from LED lights. If you’re using a standard dimmer switch, make sure it’s rated to handle the power requirements of your LED lights.

These are some of the methods that you can use to prevent LED shop lights from interfering with your radio frequencies. With a little bit of effort, you can ensure that your radio broadcasts come through clearly without any interference.

How Do You Fix Pulsing Led Lights?

Pulsing LED lights are an annoying problem for radio operators and can interfere with the reception of stations. Fortunately, there are a few different ways to fix this issue.

One way to fix pulsing LED lights is by using a variable transformer, or “variac.” This is a device that allows you to adjust the voltage level going to your LED lights, thus allowing you to reduce the pulsing.

Another solution is to install an RF filter in line with your power supply. These are active filters that can help reduce radio frequency interference (RFI). They work by blocking out high-frequency signals while allowing lower-frequency signals to pass through.

Using a Variable Transformer

Finally, you can also try installing a ground loop isolator or “RFI suppression coil” in the system. This is essentially a large inductor that acts as a kind of filter, blocking out high-frequency interference and allowing only low-frequency signals to reach your equipment.


If you have ever had the led shop lights in your home or garage interfere with your radio, then you know how annoying it can be. But there are some easy ways how to stop led shop lights from interfering with radio. All you need is a little aluminum foil and some clear tape.

With these two things, you can block the interference and get back to enjoying your favorite radio station. So next time your led shop lights start interfering with your radio, just follow these simple steps and enjoy the peace and quiet.
