How do you adjust the headlights on your 2005 legacy gt where is the adjustment screw?

Headlight adjuster screw is a grey bolt with what looks like an attached washer with serrated edges. It is located on the back side of the headlight. On the driver side, it is directly behind the windshield washer fill spout. To access on the passenger side, you must remove a portion of the air intake, which should slip off tool free with some nudging. Turn the screw counter-clockwise to raise the beam, vice-verse to lower.
