How to fix led light radio interference. First to ensure that the interference is caused by the LED light bulbs consider turning off or taking out the newly acquired LED bulbs and do a test run of the electronic device. If the disturbance in terms of picture or sound is gone then the reason is most likely evident specifically due to RF radio frequency interference or EMF Electromagnetic Frequency. How Do Led Lights Interfere With My Radio.

For an LED kit you can use a large ferrite coil and wind the input power wires around it or you can use a small ferrite coil and just clamp it over the power cable. Also both of these products create RFI Radio Frequency Interference in fact every electronic device ever made creates RFI but there are different types of this electrical interference. Sometimes when installing a LED conversion kit in your vehicle the result can be better brighter light but also a side effect of AM or FM radio interference.
Lol the LED that interferes with my FM radio is a single 12V 10watt smd. I use it as a worklight up on a wall at my shop just powered by a 12v car battery. When I turn it on the FM radio which is behind a wall from the light but speakers in the workshop side goes all static and crap.

The customer reported that when the lights were turned on it caused interference with the FM radio signal. After some research we discovered that the cause of the radio interference was due to the PWM Pulse Width Modulation circuit in the lights. The shield is usually braided aluminum or steel alloy.
Spark plug wires utilize this technology as well as many computer cables power cable Serial and Parallel cables etc. You might also get lucky by adding a choke to the wires entering the dash display andor the antenna input wire.
