illuminated surface lies not more than 250 mm from the median longitudinal plane of the vehicle.
6.13.4.1.3.              Two daytime running lamps, of which either one or both are reciprocally incorporated with another front lamp, shall be installed in such a way that their reference centres are symmetrical in relation to the median longitudinal plane of the vehicle.
6.13.4.1.4.              In the case of two daytime running lamps, the distance separating the illuminating surfaces shall not exceed 420 mm.
6.13.4.1.5.              The maximum separation distance is not applicable when the daytime running lamps:
              (a) Are grouped, combined or reciprocally incorporated with another headlamp, or
              (b) Are within the projection of the frontal silhouette of the motorcycle on an orthogonal plane perpendicular to the longitudinal median plane of the vehicle.
         6.13.4.2. In height:
         Above the ground not less than 250 mm and not more than 1,500 mm.
         6.13.4.3.  In length:
         At the front of the vehicle.
6.13.5. Geometric visibility
Horizontal: Outwards 20° and inwards 10°.
Vertical: Upwards 10° and downwards 10°.
6.13.6. Orientation
Towards the front. The lamp(s) may move in line with the steering angle.
6.13.7. Electrical connections
         6.13.7.1. The daytime running lamp shall switch OFF automatically when the headlamps are switched ON, except when the latter are used to give intermittent luminous warnings at short intervals.
         The rear position lamp shall be switched ON when the daytime running lamp(s) is/are switched ON. The front position lamp(s) and the rear-registration-plate illuminating device may be switched ON individually or together, when the daytime running lamp(s) is/are switched ON.
         6.13.7.2. If the distance between the front direction indicator lamp and the daytime running lamp is equal or less than 40 mm, the electrical connections of the daytime running lamp on the relevant side of the vehicle may be such that either:
         (a) It is switched OFF; or
             (b) Its luminous intensity is reduced during the entire period (both ON and OFF cycle) of activation of a front direction indicator lamp.
         6.13.7.3. If a direction indicator lamp is reciprocally incorporated with a daytime running lamp, the electrical connections of the daytime running lamp on the relevant side of the vehicle shall be such that the daytime running lamp is switched OFF during the entire period (both ON and OFF cycle) of activation of the direction indicator lamp.
6.13.8. Tell-tale
Closed-circuit green tell-tale, optional.
6.13.9. Other requirements
The DRL symbol in ISO 2575:2004 - Road vehicles. Symbols for controls, indicators and tell-tales, may be used to inform the driver that the daytime running lamp is on.
6.14. Emergency stop signal
6.14.1. Presence
Optional.
The emergency stop signal shall be given by the simultaneous operation of all the stop or direction indicator lamps fitted as described in paragraph
