Right....i have just found and read this for you:-

After reading it i now find that the headlights on my NC30 may well be illegal.
I have some kind of endurance fairing fitted to the front of my bike which consists of a normal headlight and a small domed diffuser light.
On dipped beam both the main headlight and the diffuser light are illuminated.
According to the legistlation a motorcycle is only allowed to show one forward facing light on dipped beam .
I work next to a VOSA station so guess where i'll be going Monday for some clarification.

Also...these amendments were made in 2005 :-
