Every other road vehicle mounts its lights to the vehicle rather than the driver...
I had a hard wipe out, front tire wash out on pavement/ice, I slammed my head with a Cygolite Triden/with battery attached to the helmet; both the light and battery got ripped off including my helmet visor and goggles. 4 cranium scans later the docs say I’m OK. I still ride with this set up but the helmet is new.
