Look I know nothing at all on this subject of modifying the tail lights with "smoking" or LED lights. Nor am I an expert on the law. I do have a degree in Optical Engineering though and worked at Xerox where I worked in that subject matter (and I'm staying at a Best Western tonight). Personally & its just my risk average nature. I would not be F'ing with the stock lighting on a motor vehickel for safety reliability and legal reasons. I do understand how people love to mess with their vehickel, its an American tradition!
Respect that!
