Federal helmet code which NYS uses…http://www.fmcsa.dot.gov/rules-regulations/administration/fmcsr/fmcsrruletext.aspx?reg=571.218
from that…
but that is for helmet manufacturers, so I dont know if it counts if you add something, especially considering it would break free in a crash
That is my exact thoughts, I mean I see no danger in it and force coming from a fall bad enough to break your neck that camera is deffenitly snapping loose first lol…
