Car Radio Interference From Led Lights

Oh it s definitely your hubby s fault kathy.

Car radio interference from led lights.

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. Coupling path conduction radiation. Lol the led that interferes with my fm radio is a single 12v 10watt smd. Cyron motor abft100 h4 digital filter removes most all static radio emi interference and canbus errors caused by led headlights.

Electromagnetic interference emi disturbance source this refers to the device emitting electromagnetic energy the source of the radio interference. After some research we discovered that the cause of the radio interference was due to the pwm pulse width modulation circuit in the lights which was being picked up by the radio through the wiring. But you already knew that. This is my attempt to rid myself of that nonsense.

We suggested installing a ferrite choke on the led leads and shipped a set of fair rite rf chokes to the customer.
