If there are still any outstanding questions on the Euro light adjuster, I have pretty much documented the install on my 190

The vacume tubing can be picked up at your local MB dealer in any length you need, the rest of the parts you can pick up at a local autoparts store.
Don't expect this mod to give you much adjustability, in actuality, its hardly worth it, as it only moves the lights a small amount
