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.

The blub plate has two off set dimples these line up with two holes in the back of the reflector, the bulb and it's holder are held in place with a spring clip. As the reflector disintegrates due to heat normal vibration wears the blub location holes eventually the bulb can move enough to causing the buzzing you can hear.
If your reflector cover rubber isn't a good fit that wont help, does to a point secure the bulb via it's holder, it's also possible your reflector is about to go west at it's adjustment mounting points again due to heat!
The head lights fitted to the Mk1 Fazer are the bikes biggest weakness just like the shock/forks!
