I bought some Holley Retrobright 1157 type LEDs to improve my rear visibility on braking and turning, but whether it's brakes or turn signals, the RFI over my radio is horrible. Interestingly, the stock mechanical flasher works just fine, and trying the electronic LED type made no difference.
JEGS suggested I buy a pack of ferrite chokes off of Amazon ($10 for a bag full) and that would fix it. I popped one on the antenna lead, no improvement. Since I had a bag full, I put a few more on, some with the cable looped around since there were various sizes in the bag. No dice. What the heck, I put them on the tail light power and grounds, nuh uh. Next I called Holley, and they want me to buy some LED load resistors.
So now, I have a LED type flasher and a bunch of chokes, and nothing is any better. Well, OK, but am I just continuing to throw money at the problem, or might this really be the fix?
