hi, one of my xenon lights has gone kaput. I called up my freindly Vaux parts man last week, and he said, "ah, it's the pre-switch, the bulbs hardly ever go", so I aks him to order me one in. Go in on Saturday to pick it up, and it seems he got me a level sensor instead. So phone up today, and someone else is in this week. He nor anyone else in the garage has a clue where or what the pre switch is. It's definetly two different things on the wiring diagram as well.
Can anyone help?
