cos my light unit is still buzzing and my thingamajig isn't even there  :groan

Check the front indicators where they go through the firing the biggest cause of buzzing.    The other is the cone and H1 blub.  Heat from the bulb turns the back of the reflector into chalk disintegrating the back of the lens which isn't made of metal.  This is the cause of the cone coming loose and the blub will start to oscillates in it's mounting = buzzing, eventually the entire back of the reflector collapses.  Daytime use of low beam accelerates the damage and there is no practical/easy way of stopping it that I know of, tell tale sign is dust in the light unit.

You've probably seen my post, i've put self amalgamating tape on the bulb holder, i think that'll help a little, although i'm still confused as to why it's still buzzing?
It's definitely the left bulb area, when i'm riding if i put my finger on the bulb wiring socket it stops, plus i can feel it really vibrating.
I may put some more tape on it tomorrow and build it up a bit and see if that helps.
