william rogers: my car had the exact same thing. As far as I know, aftermarket lights do not have the vacuum adjust...only OEM Bosch do. When I got my Bosch lights, they had the vacuum adjust. There is a little plastic nipple on the back of the headlight.

There are not many 86-91 euros over here, other than it being an SE...tell me more about your car...I'd be interested to hear.
