Aiming Area Required

It is required, since seeing the outer edges of the headlamp beam patterns depends greatly on the amount of darkness in the area, to have a specific aiming area in a darkened location. This should be sufficient for the vehicle and an additional 7.63 m (25 ft) measured from the face of lamps to the front of the visual screen.

The floor on which the vehicle rests must be flat, and level with the bottom of the screen. If the floor is not level, compensate.
