On the NY state's roadways, light bar systems are strictly prohibited. In this case, the legislation of New York specifies that auxiliary lighting with a power output of more than 33 candlepower isn't authorized. To be clear, auxiliary lighting systems are units that are fitted to improve visibility, including hazard lights, navigation lights, and off-road lighting systems, among other things. First and foremost, candlepower is a standard measurement for illumination, albeit it must be converted from lumens, which would be the measurement you are most likely acquainted with.
