I installed Euro lights a couple of years ago, and finally got around to installing the vaccum adjust feature. It took a little less than an hour. In addition to the new headlight switch trim plate and adjustment dial (which I picked up used for cheap), cost was about $35 (for a bunch of vaccum tubing - hard and soft, 1 vaccum check valve, and misc. vaccum connectors from pep boys). It was a pretty easy install. It is a pretty cool feature. For anyone with Euros who hasn't done it yet, I would recommend it because it really is pretty easy. I used the directions in the 124 Owner's Bible.

Good job man! Ill be doing this shortly to my vw, but the TDI uses motors, not vacuum diaphrams...which is good cuz my vacuum system is pretty different than a gas cars.

FYI, if you do a lot of interstate travel, you can turn the knob to "1" and then aim them like you normally would. This way, you can turn the knob to "0" to get a bit more reach on the interstate for down the road vision.

Just keep in mind that you will loose high beam distance as you do this cuz your highs will no longer be parallel to the ground. I donno if this would move your fog lamps too or not.
