    1/ The reference axis is the perpendicular to the reference plane and passes through the centre of the 45mm cap diameter.
2/ The bulb shall be colourless or selective-yellow.
    3/ No part of the cap shall, by reflection of light emitted by the passing-beam filament, throw any stray rising ray when the filament lamp is in the normal operating position on the vehicle.
    4/ The values indicated on the left and on the right refer to the driving-beam filament and the passing-beam filament respectively.
    5/ Measuring luminous flux for measurements according to paragraph 3.8. of this Regulation. Note: The R2 filament lamp is not recommended for new headlamp designs.
