Why does the READY Helmet Light only fit into one specific recess?

Children are smaller than adults and sit in a lower position on a bike, so it's important that they are as visible as possible for other road users for their own safety. 

The READY Helmet Light has been carefully designed to fit into the recess at the top on the back of the helmet. This is the highest possible position to ensure maximum visibility when it is attached to the helmet. 

Additional visibility is provided all the way around the helmet thanks to all the reflective features (straps, logos and detailing on the size-adjustment dial).
