Radio turns to static when I turn the headlights on

Just like the title says, every time I turn my headlights on my radio instantly turns to static. If I pull the headlight switch one notch to turn just my side markers on the radio does not turn to static, so it only happens when my headlights are actually on. I checked all my grounds and they all look somewhat decent. I have a new retro sound radio, new kick panel speakers, and a new antenna from classic industries, it did the same thing with my old radio as well. I also have some nice led headlights from octane lighting. And yes I have the antenna plugged into the radio. Any ideas? I'm wondering if I should add some grounds or something. It sucks because I can't really listen to the radio if i'm driving at night. Thanks.

Re: Radio turns to static when I turn the headlights on

What type of distributor do you have?

If you suspect a ground issue, definitely remove, clean and reattach all grounds. Then add extra grounds! You cannot over ground something.

Thanks.
Just a thought, did your old radio have static with incandescent headlights?

Re: Radio turns to static when I turn the headlights on

New LED headlights produce FM static, and that interferes with your radio. You'll need to get some Ferrite bead choke, or RFI noise filter. You put those around the cable by the headlight plug. You'll have to do some research to find out what ones you'll need for your application. I put LED headlights in my '02 Silverado and my wife's '06 Avalon and needed to put those on both vehicle.

Thanks! It was driving me insane, literally! I will definitely have to look into it. My distributor is a new HEI Ac Delco.
