I installed the Rivco Handlebar Illumination kit, with little problems. The directions were ok, and they look great, especially at night. But yesterday was the first time my wife had ridden with me, and we had the intercom system on. We both heard a high pitch whine, which was constant. The noise would lessen as I turned the lights down, until the noise quit as there was no illumination on the Rivco lights. Any one else had this problem or has a suggestion as to what we could do. The radio drowned it out, some, but still I don't think it should be there.
