Radio distorts when you turn on vehicle lighting?

It's Monday morning and the work week has begun again. After a cup of coffee, it's really time to get started. A new collection of LED work lights has just arrived and you can't wait to get started. After the lights are mounted on the vehicle, it's time to test the lights! When you turn the lights on, the radio starts to interfere. What? Not now! When this situation occurs you will probably curse the radio. Often the first thought is that the radio is interfering due to poor reception or range, but it is also possible that the radio is interfering due to turning on the lights. In this case, the collection of work lights does not have the proper EMC interference.

How is it that the radio interferes when the lights are turned on?

All electronic devices can be a source of electromagnetic interference. An interference can cause an electromagnetic noise or an unwanted signal on your radio. In addition, the screens in your vehicle may also begin to flicker. The problem is often in the LED lights themselves. For example, the LED lights emit too much electromagnetic radiation. When these are connected to the same bandwidth as the other electrical devices then this causes interference.

Furthermore, it is also possible that the LED lights are interfering with the radio through the wiring. It is possible that the interfering signals are picked up directly through the wiring. Once the cause of the electromagnetic interference has been determined, the solution is often found quickly. Consider, for example, better shielding of cabling, systems and cable sizes.

How can the radio interference be remedied?

If your radio interferes when you turn on the lights, then you would do well to replace the LED lights with higher quality bulbs. If you search for LED lights on the Internet, you will see many providers who sell LED lights at competitive prices. We would like to advise you to look beyond the purchase price. It is of course not nice if your LED lights interfere with the radio. Make sure when purchasing that the lighting has an EMC certificate! This prevents the LED lamps from interfering with the radio.

Another feature you might want to look for when purchasing is an official CE mark. If an electronic device has an official CE mark then this device automatically meets EMC requirements as well, as this is one of the features that a device must meet to be CE marked.

Radio disturbs when turning on the lights, from now on 100% history!

LED lights that interfere with the radio are now a thing of the past with LED lights from TRALERT®. In our range you will find EMC interference lights of different strengths. Our new collection of LED work lamps is even equipped with a CISPR25 Class 5 interference suppression. In the automotive electronics market, CISPR 25 is an increasingly popular benchmark and requirement for body electronics. Electronics suppliers are increasingly focused on proving that their devices can comply with CISPR 25. The class indicates the level of suppression. Curious about the products that feature the new CISPR 25 Class 5 suppression? Then check out this collection on the dealer portal.
