What does adjusting the headlights of your lorry's lighting system involve?

Correct answer

Adjusting the beam projected by the headlights vertically and horizontally

Headlamp aiming adjusts the beam’s vertical and horizontal direction to the vehicle specification, providing correct illumination without dazzling. Prepare the vehicle and measuring equipment according to the manufacturer’s procedure. A beamsetter can check alignment; a wall may be used for a specified procedure but is not universally required. Horizontal adjustment alone or changing beam width does not describe complete aiming.
