The Tozuda Head Impact Indicator attaches to the back of any helmet. This device will turn from clear to red if the helmet is hit with a significant force. It will NOT turn red unless the helmet is hit with enough force warranting the necessity to check the head of the athlete. All users have to remember is, “If it’s RED, check your head!”

The product is available for ages 8-13 for Youth and 14+ and up for Adult. 

Please note that the Impact Indicator is not an indicator of if/when your helmet should be replaced. Follow manufacturers' guidelines for helmet replacement and ensure that if your helmet has made impact with the ground in a fall or drop, it should be replaced.
