Whether you get hit helmet to helmet, or hit the ground hard, you should know when you need to get checked out.

Head Safety in Football

Tozuda Head Impact Indicators will alert players, coaches and parents of potentially damaging impacts. Football is among the most high contact sports being played today, be more aware of its risks and know when a player has been hit too hard.


Whatever helmet you have, Tozuda is built for you to attach it. Using just double-sided tape, our Indicator sticks onto any existing helmet.


All you need to remember is "if it's red, check your head." Our Indicators turn from clear to red when hit with too much force, so you know when to get checked out.

Weather Friendly

Playing inside or outside, the Tozuda Indicator uses a tape thats rated from -40°F to 200°F, so whatever temperatures you're playing in, Tozuda has your back.


Tozuda Impact Indicators can withstand normal hits, but activate when they need to.

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!

How It Works

Whether you're skiing or snowboarding, know when you've fallen too hard.

What Happens If I Drop My Helmet Or Throw My Bag With The Helmet In It. Will It Activate?

It can take an impact below its threshold, but once it passes that danger zone of force, it'll turn red. We want to make sure our athletes are being safe with their helmets and treating it like it's their head. Some helmets are not effective after a major hit, including even being dropped on the ground! Our indicator is a great way to realize when those drops happen, and think about potentially/maybe replacing the helmet if it dropped hard enough to activate.

Will the Indicator fall off my helmet while I’m playing?

We use aerospace-grade double-sided tape to attach our Indicators to helmets. The tape is rated for over 230 lbs of shear force, which is comparable to the weight of a refrigerator!

I Play Lacrosse But Also Play Football During The Fall. Can I Use An Indicator In Football Too?

Yes! Because our Indicator attaches to any helmet, it’s so easy to use on different helmets in different sports. You can get extra tape from our store to attach your current Indicator to a new helmet, or purchase a new one to equip all your helmets with Tozuda’s technology.
