LED headlight install now radio is static

I don't know of one but I've heard many of the after market lights exhibit that problem.
Good idea 14POSE. I DO have the HD Daymaker AND the internal fairing antenna. No static with OEM.
There are several on the internet, here's Harley's. This is what I have but bear in mind-I seldom have the radio on but when I do, no static with the OEM Daymaker.
All these lights create RFI, (Radio Frequency Interference) from the 'driver'...in florescent lights, thats the ballast. Sometimes when I'm in the garage with the radio playing and the lights are on, I hear it thru the speakers. The LED lights from JW Speaker and HD have better shielding on the cables and the light to alleviate RFI's.
The solution might be what is called a ferrite coil, also known as a ferrite bead, a ferrite choke, or an RFI choke. All of these names mean the same thing. Ferrite beads prevent interference in two directions: from a device or to a device. A conductive cable such as the input power for the LED headlight bulb acts as an antenna – if the device produces radio frequency energy, this can be transmitted through the cable, which acts as an unintentional radiator. In this case the bead may be required to reduce RFI. Conversely, if there are other sources of RFI, such as an ignition module or battery charging alternator, the bead prevents the cable from acting as an antenna and receiving interference from these other devices. I've attached a couple pics of ferrite coils. The first you've probably seen on the end of a USB power cable. The other is an RCT2 RFI Radio Frequency Interference Ferrite Chokes and it just snaps on the cable. Here is one place to get it but they sell 5 for $10....you should only need one...or two.

I believe the lamp sits in a metal frame. You should have a ground wire in the front end already, try attaching that ground to the light frame to bleed off any excess electricity. Just tape it to the metal and try it, if it works you can solder it on better.
Some halo rings have a separate power and ground wire that need to be wired in. Where did you connect both of those wires from the halo? Wondering if you tapped in to something that's causing the static, but if you changed it so the halo is spliced in to just the headlight wiring, maybe it would help
