hi
not seen any where thats does refurbed headlights for Jaguars
its just as easy do yourself, I did mine on my S-type and its a very similar procedure on the X-type
only takes a few hours, common fault is the adjuster break and the light go droopy and only light just in front of the car, better adjuster available on ebay
they come apart quite easy just pop them in the oven on about 80 to 100 deg for 10 mins, then the black, blue tak type sealer goes soft and they just pull apart, once there unclipped
once the cleaned, new adjuster fitted and rebuilt, use a scotch 3m headlight restore kit to polish the lenses so they look like new
theres videos on youtube show the procedure on X-type lights
cheers
Joe
