Bought 530 (2004) from Japan and now it is on the way to Finland. Have one problem because need to change the head lights from left side drive to right side. Having xenon lights (projector). Any easy way like in some other German cars? Thanks...

Assuming you have non adaptive headlights, unfortunatly its new headlights.

If your looking to sell your RHD headlamps you would be able to sell them in the UK who also drive on the right.
