Technical How to earth headlamp to stop buzzing when lights on?

[Hexham]

Anyone any ideas how to stop the headlamp buzzing when the headlights are on? Looking on forum it seems could be an earth problem. Any ideas how to fix it? Thanks in anticipation of a reply.

I'd pull the hight adjustment motor connector off and see if the buzzing stops


Earth's on the shuttle

Check the bulb plug for arcing

The body computer plug can melt but nothing should be heard from outside the car
