Highly reflective, fit easily and securely to the pushchair/buggy. A new innovation in high visibility. Pro-actively improving visibility in darkness and low light situations. Baby carriers are particularly vulnerable from a visibility viewpoint, and, as they enter the road first, it is important that they are highly visible immediately to oncoming traffic, in urban and rural situations. The discs, attached to the front and rear wheels, become highly visible through the spokes or otherwise when light strikes them. This actively enhances visibility, and therefore enhances the safety of the child.
