Safety reflectors - they don't have a clue :(
Non of the products on this board can be called "safety reflectors", Products displayed here can make you feel special but do not meet the requirements to save your life when needed.
Ones who have made those products don't have any acknowledge in safety matters therefor it is understandable they call everything reflective "safety reflectors".
All these products are additional reflective accessories. If the aim is to be visible and safe don't forget to use a real reflective product too!
