Swannymere you make me chuckle. Your short to the point one liners are so on keeping with your avatar!
It's not just the light assembly but my 999 has a small number plate relocator which basically screws into the rear of the number plate light. The wind has made this very lose and it looks like the whole thing could fly off at any moment.
I feel the whole thing could be sorted in one. The Ducati9 at least has the plate holder included.
