Good stuff AndrewM.
Xenons fitted tonight, didnt need to remove the bumper completely, just pull it away to access the side screw.
Its a totally straight swap even down to the wiring plugs.
For people who don't want to install self levelling, you can swap the halogen (0,1,2) leveller units into the xenon units, they twist 1/8th of a turn and pop out. That enables you at least some control over your xenon beam aim.
Stunning results as well, look really good.
Keep us posted how it goes
