I found this site from the State of New York Assembly about Vehicle and Traffic Law, it doesn't mention anything specifically to off road lighting. Only this:"No light having a candlepower rating in
excess of thirty-two candle power shall be used on any vehicle, unless
it is of a type approved by the commissioner."
This is the website, maybe someone can have better eyes and find something related to off road lights!
