| Not one I'm aware of!
Is it purely bike related?
If so, it will be post 2003 as ST's using both beams together were type approved for 2003 - not sure if the new ST uses both filaments on main.
Although I don't have my reference books to hand, the only thing I could hazard a guess at is an EC directive of some sorts - I'm certainly not aware of any UK legislation along these lines.
If it's an EC one, it will relate to new vehicles from the inception date of the legislation - they are not retrospective.
If I find anything when I get back to work, I'll let you know.
