Sensitive: Certain frequencies produced by electronic devices may disturb other electronics that are sensitive to those frequencies.

It doesn't matter if it's an automotive application or a household appliance: Ferrite rings are a common method to curb these disturbances.

How does it work?

A ferrite bead or core can be added to an inductor to improve, in two ways, its ability to block unwanted high-frequency noise.

First, the ferrite increases inductance, concentrates the magnetic field, and therefore reactance, which filters or impedes the noise.

Designed: To be used on the output cord of any HID ballast or input wiring on an HID bulb, regardless of OEM or aftermarket parts; If your radio is picking up static from your new HID system, these will help.
