• one independent front position lamp may be fitted above or below or to one side of another front lamp: if these lamps are one above the other the reference centre of the main-beam headlamp must be located within the median longitudinal plane of the vehicle; if these lamps are side by side their reference centres must be symmetrical in relation to the median longitudinal plane of the vehicle,

• a front position lamp that is reciprocally incorporated with another front lamp must be installed in such a way that its reference centre is situated in the median longitudinal plane of the vehicle,

• two front position lamps, one or both of them reciprocally incorporated with another front lamp must be installed in such a way that their reference centres are symmetrical in relation to the median longitudinal plane of the vehicle.
