Default Re: when the defrost is on the radio gets static

I acquired radio static/interference after installing the LED license plate lights. Of course,it happens only when I turn the lights on. It did this with both the OEM head unit, and my new quality aftermarket head unit. I don't know if these two issues are related or not ; but I'd sure like to know the cause and the fix; (and for me anyway) without having to go back to the incandescent. As 180 has mentioned; the common denominator is the general location of the rear defroster element, the license plate lights, and the antennae. In my case, I don't believe I have any shorts. Another member has also suggested that I open up the back hatch panels and separate any common ground back there.
