A few states have their own headlight regulations, but most just incorporate the DOT (Federal) standards, either explicitly or by reference. If New York doesn't have their own separate requirements, then DOT regulations will apply. The DOT headlight height spec requires that the central axis of the lamp be 22 to 54 inches above the road surface.
Some states still have laws on the books that specify a higher minimum height than DOT (e.g. 24 inches), but still allow cars
manufactured in compliance with the lower DOT requirement. However, if you are
modifying your car or
retrofitting it with aftermarket headlights (i.e. equipment or
installation different than OEM), the state requirement will almost certainly apply.
