I have Euro lights with the levelling feature, but have not connected the units. Some Euro lights have the vacuum actuators built in, most aftermarket lights don't, even if made by Hella or Bosch OE suppliers, unless you specifically order them that way at extra cost.
An article in the Star described the part numbers and connction features. IF you have the headlights with the actuators, all you need is some vacuum line, Y adapters, and a Euro faceplate for the headlight switch that has a 4 or 5 position roller switch, a bit like the center console fader.
The Actuators are black cylinders inside the back cover of the headlight housing about the diameter of soup cans. You can't miss seeing them if you have them. If you don't, you need different lights. Like I say, I have the actuators, but have never hooked them up - my lights are MB Euro Hella units off of a dismantled gray market w124, and have the MB number and logo on them.
Hope this helps.
