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.
