Xenon headlights usually have a flat beam,so you may not need to do any adjustment.Also make sure the rear fog is on the right side,if only one fitted,and the speedo is able to read in mph.

Who ever it was that said Xenon headlamps are flat is wrong ... Xenon headlamps come in various types, it refers to the bulb and electronics not the dipped light settings (I have Xenons, exactly the same light set up as haloglen, just different bulb and electronics).

VWMan, I suggest you check with breakers yards and scour Ebay / Gumtree and other online auction houses in your search for replacement headlights, it will be much cheaper than buying new lights from the dealer. If you have only single rear reversing and fog lights you may need to replace the rear lights, slightly more complicated job here, so that the left is the reversing light and right is fog lamp (pity EU does not enforce twin reversing and fog lights, it would be better all round, but that is off topic)
