Fellow XJ8 owners/drivers/enthusiasts - a real quicky! I have read ALL the threads to ALL headlight adjustments...and I have been personally adjusting/aiming headlights since I was a just a young kid - but the adjusters on my 2005 throw me for a loop? I fully understand the vertical as well as the horizontal - as in all types of headlights, I have even found very explicit photographs from members showing their locations - all well and good! The photographs even go as far to show the 'Round' hole in the one adjuster - but no-one calls it out! How the heck do you turn that adjuster - if it's round?? Maybe this is supposed to be factory set - and you're not supposed to fool with the setting?? The other adjuster has the hex key recess - more understandable.
I'm sure it's an easy explanation that i have totally missed.
I lokk forward to feeling foolish!!
