| 6.2.3.1.2. | A headlamp producing the principal passing-beam, that is reciprocally incorporated with another front lamp, must be fitted in such a way that its reference centre lies within the median longitudinal plane of the vehicle. However, when the vehicle is also fitted with an independent driving-beam headlamp, or a driving-beam headlamp that is reciprocally incorporated with a front position lamp alongside the headlamp producing the principal passing-beam, their reference centres must be symmetrical in relation to the median longitudinal plane of the vehicle. | a0c0 |
