Thanks for your help guys. I was asking because a know all on another bike group who is an ex police officer (alledgedly) claimed that the law was brought in during the 60s because drivers were mistaking bikes for cars in the distance due to of all things the 2 small sidelights on some Royal Enfields (Ask your dad

)
He has now had to admit he is wrong for the first time in the 3 years that the list has been going
Thanks again
