New York is the only state I recall having a motorcycle inspection. They more or less just checked that you had lights.
(d) Headlamp.
1. Check presence/condition. NOTE: Certain motorcycles may have a head lamp system that "modulates" between high and low intensity. This is an allowed modification only if the system can be switched off for normal operation. Reject if: 1. Not equipped with at least one approved, operating motorcycle headlamp. Lamp is not operational; not properly and securely mounted, lens is cracked, broken, covered, discolored or obstructed (such as shields, paint, etc.). Light is not white or does not operate properly in all switching positions. Lights do not have high and low beams.
(e) Other lights.
1. Check tail, number plate, stop and turn signal lights, reflectors. NOTE: No lighting other than the headlamp(s) referenced in subdivision (d) of this section may be modulated; they must emit steady light. Reject if: 1. Vehicle is not equipped with at least one tail and number plate light. If manufactured after October 1, 1968, one stop lamp. August 1985 and newer motorcycles must have turn signals. Does not have at least one Class B red reflector on rear (may be part of light lens).
I'm interested in lighting up the road better, but there seems to be such a wide array of opinions about what works well that I feel I'd end up buying and installing a few different options before I found something I was satisfied with. The S7 that Clay used is the only one that made it into the wiki for the X platform. Has anyone else used this?
