It can't weigh more than my fiberglass motorcycle helmets weighed when I used to commute to work wearing a helmet. How much does that light weigh that it causes a problem with your neck? Highway wind speeds with a motorcycle helmet gave me good neck muscles years ago.
But if you sprained something in your neck, might take a few months of light duty to heal. I am not questioning what you need to do to heal.
