Review on VSKEY Clip-on Noise Filter [10pcs 13mm]: High-Frequency Ferrite Core Choke for Subwoofer, Amplifier, Speaker, Video, Radio, Home Power Audio Device Coaxial Cable [0.5 inch Inner Diameter] by Eric Surabhi

I have a 1997 Mazda Protege DX with a radio installed, I am restoring it because it was my mother in law's car and she died about a year ago and I will be restoring it and giving it away to one of the kids while When I did this I installed some hidden ballasted LED spotlights, after doing it I could almost only catch a few radios due to all the interference when the lights were on. I've done some ferrite research and seen this product I've now bought and once I installed them in series between the LED ballast in the headlights about 90% of the static was gone and I was able to pick up my radios. Since then I've bought more ferrites and installed them on my radio antenna as well as the leads coming out of my alternator and they seem to do a pretty good job of reducing the static noise you get on the radio in some cars when it's your turn the signals are flashing and off and so on, if you have such a problem, i think it's worth a try.
