I always carry a copy of the attached in my motorcycles with headlight modulators. It is a PDF file with the complete U.S. and Canadian federal regulations. That way I can show an officer the regs without arguing at all. If he/she chooses to ignore the regs I can turn my headlight to low beam. But at least he/she would have seen the regs and, perhaps, accepted them. Indeed, he/she would be welcome to keep my copy.
That said, I have never been stopped.
If you want to print out the regs, be my guest.
