Fixing LED Headlight Radio Interference

September 15, 2019


After putting in some LED headlights in my truck I noticed I’ve got a problem. Hope I don’t get a copyright strike for this. Radio with the headlights, off and with them on. off. on. What the crap! I thought I might try something to see if I could fix it so just bringing you along for the ride to see if it works. These are ferrite clips or ferrite cores ferrite chokes. They go by a couple different names but basically what they are is a filter against electronic interference. You commonly see these wrapped around the cords of chargers for laptops and stuff like that. Inside you can see there’s a ferrite ceramic core that wraps around the wire. You lay the wire in here, close it up clip it shut, and it basically gets rid of all that electronic interference that I’m hearing through the radio. So we’re going to give them a try today and see how they work. I got these off of Amazon from a company called the EBoot, I’ll put a link in the description to those guys. I’ve actually got a couple of their products before and they’re pretty good. This happens on just about every FM station. You can turn on the headlights, and most of them you can’t even hear at all. Some of them come in more clearly but I think it has a lot to do with how close I am to the radio station itself. This is ridiculous. Here we are behind my headlight. I’m going to stick this thing on the wire that goes from the power plug to the headlight on the headlight side, and see what that does. I already did the other side so let’s see what happens. It’s a little bit better. Guess we’ll add some more. Can’t forget the fog lights. So glad I zip tied all this stuff up. It’s even better than it was before so. Guess I’ll add another one. I even put one on the little fan wire. This is an electric motor it could be the cause of the problem too. So far I’ve got three on each. Okay so i think i got it nailed down. The fog light ones when i leave just the parking lights on which are not LEDs at all and I flip the fog lights on and off I don’t notice any difference in the radio so i think i got it nailed down to the headlights and there’s only like one more wire that I could possibly put one of these things on I’m gonna give that a try and see if that makes any difference but it’s much better than it was just not good enough so I keep on trying. Tell you what, I didn’t think it was going to need all these extras but I’m sure glad I got them. I mean, the pack was only eight dollars so i don’t really care but i was going to have to just store these for a rainy day. Looks like today is that day! damn it! I actually added one more of these clips onto the little wire that comes from the box to the fan and it made it horribly worse on every station so i took that back off it kind of felt like the Christmas Story dad where he has all that mess of plugs on the wall and it starts on fire. Just one too many! You know that one station that still has a little bit of static you know I hardly ever listen to it anyway so I don’t really care. The rest of the stations i listen to are great! These are the LED lights by the way. They are a generic actually I don’t even know what the call them. A bunch of different companies that carry these and they’re all different names so good luck if you want those but these are really good lights so far I’ve got all but one or two stations that have come back without any kind of interference so I’m just going to go with it but if you’re having the same problem give this a try see if it works out for you. All right, so ferrite clips. I ended up using almost my entire pack. This is all I have left. I’ve got all but two of my stations back with no interference at all. For as cheap as it is it’s, worth a shot. If it doesn’t work you can either keep them for something else or send them back or whatever. Now these things actually come in quite handy you can use them for a lot of other things like if you have a phone charger that makes noise when you plug it in or something in your house interferes with your stereo or your TV or something like that try one of these things you might just work. So these things are going to go in the drawer for some other time

    Looping the cable Around the core up to 7 times increase the effect

  • Reply Gene Conti April 25, 2017 at 6:07 pm

    So, I have the same truck as yours. I have also tried the ferrite cores and no luck. I even "stacked" them 3-up on the lines and no difference. …any thoughts?

    thanks have this problem in tractor when i put on led beacon ,will try this

  • Reply DERMOT HENRY August 3, 2017 at 9:59 pm

    just wondering should you put the ferrites on the radio wire?

  • Reply DERMOT HENRY August 11, 2017 at 7:43 pm

    yes i put these ferrite core clips on a led beacon in tractor on the power wire,this worked a treat ,no more interference on the radio,had the clips on the earth wire first and didn,t work ,thanks rocket scientist

    if LED light bother in the car radio…
    try change different normal higher brightness sylvania silverstar ultra headlight bulbs…
    it would not bother to the radio

    Rocket Scientist, amazing, GMTA! Every light in my truck is LED. Going to give this a shot. My LED's came with canbus so I know that isn't the fix, but may be the problem. I had my driver rear saying bulb out, unplugged it and rotated it 180 and solved that. Lets see if this works on the radio noise. Thanks!

    You should have tried putting some on the power to the radio and also if you have enough wire you can go around and pass thru a couple times with more success or just adding more of them to the same wires

    Thanks man. I just purchased these farite clips for my Harley ultra classic. Installed led headlight and lost all radio reception. Hopefully it solves the problem.

    Any idea if this solves AM station interference? All LEDs, but just added LED to factory driving lights. Interference came up like a wall!!

    How many Ferrite Rings did you use in each spot?

    Mine just started to happen. It worked fine at first.

  • Reply Matt Greenland May 22, 2018 at 1:25 pm

    I think it has something to do with the radio antenna ground. I have the same issue but with LED brake lights. There no static when the sourcing from a USB instead of the radio signal.

    Thank you for this video! I installed new led fog lights and had the same effect on my radio. This was a fix!

    Thanks bud, I have the same vehicle with the same problem after installing LED's. Your video was very helpful

    Get the dash cancellation message hide plug for the light bulb size you have , it's a plug that plugs between the bulb and the main harness. Ebay for $9.00. It's a HID plug. Has a black box in the middle plugs on both ends

    Did the led lights effect the sound on your CD or MP3 player?  Thanks.

  • Reply David Peric July 26, 2018 at 9:16 am

    maybe buying a fanless led bulb wouldn't have this problem

  • Reply Andrew Scharbarth August 21, 2018 at 7:31 pm

    Ferrite cores work better when you add multiple turns of the wire through them.

    Another thing you can do to get rid of interference is ground the back of your radio better with a bigger ground

  • Reply Miles Kudo January 7, 2019 at 3:09 am

    Very helpful, I was getting RF interference big time after I installed my SL1 LED headlights. I ordered a set of #10 5mm ferrite beads from Amazon. I only needed one for each light to totally eliminate all the interference.

  • Reply Levi Bridwell January 20, 2019 at 12:36 am

    Ive had that exact type of led bulb before, first type/design I ever tried. Ive now had a few different sets and found the cob designs suck and you want a bulb w like a cree xp70 or two on it kinda thing.. but the filter is an interesting idea. It would work better on the speaker wires. Or a diode at the fuse box to ground I think..

    Gee, the 5 dollar bulbs that used to be in there didn't have that

    Does this really work? For radio shooting problem .. And how many mm should Ferrite be..?

    If you have enough cable it helps to wrap them in a loop around the magnet.

    Just unplug the fan and try it.

    Thank you so much! I replaced the radio in my Jeep after not having one for 5 years and I t had amazing quality but i noticed at night it was shit so I did some research came here ordered the clips and boom, fixed.

    So I have a led emergency blue light bar and it will do this with my firedept radio and pager. Would these things help with that?
