As the law here in NH is written, they may be illegal here as well. I believe the law says 'it is illegal to illuminate game animals'. I had a talk with a CO about a laser sight (which are illegal because of the 'illumination law') so I would imagine the lumenock would fall in the same category. I don't think a CO would bust you for that unless he was piling charges on you for doing something much bigger you shouldn't have been doing.
