Axis of reference definition
Axis of reference. (or "reference axis") means the characteristic axis of the lamp determined by the manufacturer (of the lamp) for use as the direction of reference (H = 0°, V = 0°) for angles of field for photometric measurements and for installing the lamp on the vehicle;
Axis of reference means the characteristic axis of the light signal determined by the manufacturer of the lamp for use as the direction of reference (H = 0°, V = 0°) for photometric measurements and when fitting the lamp on the vehicle tractor;

Axis of reference means the characteristic axis of the light signal, determined by the manufacturer for use as the direction of reference (H = 0º, V = 0º) for photometric measurements and when fitting the reflex reflector to the vehicle.
Axis of reference means the axis to be defined by he manufacturer of the retro-reflecting device, which serves as reference line for the illumination angles in photometric measurements and in practical use. The axis of reference usually corresponds to the axis of symmetry, if any, of the illuminating surface.
