When working on the headlights on these is a lot easier if you take it out.Lift up the grille ,undo screws and pull light forward.Unclip the back cover of the light and run another lead from the black wire of the headlight bulb direct to an earth point or battery.If this improves the situation then you have an earth fault.May be easier/quicker to run a new lead than find out where the fault is.hth

As elekie&a/c doctor suggests, finding earth termination points can be a right pain. Manuals will normally only indicate where earthing points are common (in the wiring diagrams) but not necessarily the physical location.

Far easier (if it is an earthing issue) to simply run a wire from the rear of the lighting plug to a local earthing point.

Question you might want to ask yourself though is, are there any other circuits, possibly using this earthing point ? (It might be worth a cursory investigation following the harnes to see if you can see an earth termination point).......ebt

(ps, it'r pretty easy to create a new earthing point)

Maybe you could update us when you've done some fault finding...

Any news ???.......ebt

Sorry for the lengthy time since my last reply.

No news yet I'm afraid, haven't had much time to deal with it. I'll update you when I've checked it out

Bump for resolution information ...
