03 Boxster headlight adjustment confusion

[tcora]

All: I am confused by the headlight adjusters in my 03 Boxster. The lower adjuster is supposed to raise and lower the light and it does. The upper adjuster is supposed to move the light laterally, but, instead, it also raises and lowers the light. Neither adjuster moves the light laterally and both move them vertically! This is true for both headlights.

Anyone out there have the clue I am clearly missing?

Thanks.

The lower adjuster is only raise and lower, the upper adjuster is left and right but at the same time up and down. For example, the head light is too much to the right - turn the upper adjuster till the headlight is in the perfect left/right possition, but the light is too high now - adjust with the lower adjuster the head light downwards till the perfect up/down possition. Repeat if necessary.

Is this true for '99 2.5 as well?

This rule obtains for all Porsches, the pivot possition point of the parabola/lens is the culprit.

Thanks RFM.

This was driving me nuts too. **** owner's manual does not give a hint why both adjustment screws appear to to up/down only.
