Typically not the case so I doubt it.
Everyone else can stay out of it because the Germans control almost all EU regulation ... including bike lights. Without German regulations, we'd still have expensive and poorly engineered dynamo lighting system (or the junk that one sees in the US like Magic Shines.)
The market forces (i.e. return on investment) have to be there or no one builds anything no matter what the regulations are.
