I have just joined this forum and I am looking for some opinions regarding the use of "Tireflys" lights, those that you screw into the valve in the tyre. I am trying to make my bicycle visible at night, for the commute home from work, and I thought these would help making me more visible. However I am not sure if they are legal, as they state on the pack that they are suitable for off-road use only, although they also advertise them as great for night visibility. I am thus confused, and not sure if I should install them or not in my wheels. Also, I am new to the USA (Corvallis, Oregon) and I am not sure what is appropriate here.
Best Regards to all,
