Adjustment horizontally is done by turning the **** located on the high beam side of the housing(closer to the vehicles center). Turning that **** counter clockwise will move the beam towards the right. Keep the beams pointed down and to the right. DO NOT point the beams straight ahead or too high as you will blind oncoming cars. The ***** may be covered with a cap which you will have to remove. Use an allen wrench to reach into the plastic tips of the ***** to turn them.
