2012 GL1800 Radio Static after LED Headlight Installation

Post by joberry1 » Fri Mar 30, 2018 7:49 pm



Hi, looking for some input for an issue I have after installing LED Headlights. I purchased and installed the new Pathfinder LED headlights for High and Low Beams. I also installed the Pathfinder sequential running/turn signals and the spoiler sequential light. After installing the headlights, I noticed static on the FM Radio. The static increases when I switch on the High Beams, enough that you can't really hear the radio, only the static.

I contacted SoCalMotoGear via e-mail yesterday also. The said that they hadn't heard of this problem. Asked me to make sure the drivers were not in contact with the antenna or radio wiring in any way. Pulled boxes back out to access the high beams this evening. When I unplugged the high beams, the static was gone. It appears that most of the static comes from the right side high beam, but there is drastically less from the left as well. With both unplugged, the static is gone and the radio plays fine. I left SoCal another e-mail tonight, but would expect not to hear back from them until next week now.

Any ideas or suggestions. Thanks in advance.

I have heard of that problem, no answers for you though. I just put LEDs in mine also but I don't listen to radio so I don't care. I did turn it on though just to see and didn't hear any static. I just have them in the low beams though.

It's a known problem for some LED headlight bulbs, that have poorly shielded drivers, or drivers that allow noise to flow back into the power wires, which then act as transmitting antennae. It's the first time I've heard of it with Pathfinders, however.

I would try putting a ferrite choke on the headlight wires as a test to see if it cuts down on the noise at all - place them as close as possible to the headlights/drivers. That should block any RF from getting past and being broadcast to overwhelm your radio.

Thanks Wingadmin. I will try that. Not knowing much about electronics, does it matter which side of the driver I put it on? (input side or LED light side)? I will post the findings after the test to maybe help someone else later.

It depends on where the noise is coming from! Try each and see what happens. If you can, loop the wire through the ferrite core, the more times the better:

Choke on wires
