In height: a minimum of 250 mm and a maximum of 1 500 mm above the ground. 6.14.3.3. In length: at the front of the vehicle. This requirement is considered to have been met if the light emitted disturbs the driver neither directly nor indirectly by reflection off the rear-view mirrors and/or other reflective surfaces on the vehicle. 6.14.3.4. Distance: — if the distance between the front direction indicator lamp and the daytime running lamp is 40 mm or less, the electrical connections of the daytime running lamp on the relevant side of the vehicle shall be such that either: — — it is switched off, or — its luminous intensity is reduced to a level not exceeding 140 cd, — during the entire period (both on and off cycle) of activation of the relevant front direction indicator lamp. 6.14.4. Geometric visibility: — α = 10° upwards and 10° downwards, — β = 20° to the left and to the right if there is only one daytime running lamp, — β = 20° outwards and 20° inwards if there are two daytime running lamps. 6.14.5. Orientation: — to the front; may move in line with the steering angle of any handlebars. 6.14.6. Electrical connections: — all daytime running lamps shall light up when the master control switch is activated; however, they may remain off under the following conditions: — — the automatic transmission control is in the park position, — the parking brake is activated, or — prior to the vehicle being set in motion for the first time after each manual activation of the master control switch and the vehicle’s propulsion system, — daytime running lamps may be manually deactivated; however, this shall be possible only at a vehicle speed not exceeding 10 km/h. The lamps shall be automatically reactivated when the vehicle speed exceeds 10 km/h or when the vehicle has travelled more than 100 m; — daytime running lamps shall in each case be deactivated automatically when: — — the vehicle is shut down by means of the master control switch, — the front fog lamps are activated, — the headlamps are activated, except when they are used to give intermittent luminous warnings at short intervals, and — in ambient lighting conditions of less than 1 000 lux where the indicated speed on the vehicle’s speedometer is still clearly legible (e.g. when speedometer illumination is always on) and the vehicle is not fitted with a non-flashing green tell-tale in compliance with point 6.5.9 or a dedicated green circuit-closed tell-tale for the daytime running lamp identified by the appropriate symbol. In such a case, the passing-beam headlamps and the lighting devices required in point 11 of Annex I Section B shall be automatically activated simultaneously within two seconds of the ambient lighting level dropping below 1 000 lux. If the ambient lighting conditions subsequently reach a level of at least 7 000 lux, the daytime running lamps shall be automatically reactivated, while the passing-beam headlamps and the lighting devices required in point 11 of Annex I Section B shall be deactivated simultaneously within five to 300 seconds (i.e. fully automatic light switching is required if the driver has no visible indication and stimulus to activate normal lighting when it is dark). 6.14.7. Circuit-closed tell-tale: — optional. ▼B
