Actually, some of the Euro lights do not have self levelling actuators. The Hella site
lists the units available both with and without self levelling, (footnote 4), and the IMPCO/Performance rep I talked to before I got my gray market units said they did NOT have self levelling. (maybe he was mistaken, but the shop in san Diego where I got my gray market lights also had new Hellas without level adjust actuators.
Check for those actuators before buying the faceplate and tubing. The Star article is the one at the link posted above by Blaubenz_MB.
