Thanks for the info.
So what I am looking for is a pair of these http://www.ebay.co.uk/itm/BMW-5-Series-E39-Hella-M-Tech-Headlights-Angel-Eye-Headlamps-Lights-M5-535-530-/191516126511?pt=LH_DefaultDomain_3&hash=item2c97402d2f I cant seem to see a ballast here? Should it not be attached to the rear of the headlight unit?
I have a levelling dial on my dash, but thats just for manual adjustment when ride height of vehicle changes. How complicated is it to install auto levelling?
Im actually shocked by how bad the OEM lights are, its terrible when its rain or on dark country lanes, you can barely see anything with oncoming traffic.
Will a light bulb change make any difference? My lenses aren't clouded.
Appreciate the heads up, will be a bit of a ball ache replacing entire headlight unit ever time I need a MOT. Although being able to see when im driving will be nice!
