shall remain capable of being actuated even when the device which controls the starting and stopping of the engine is in such a position that operation of the engine is impossible.

       6.10.  FRONT FOG LAMP

       6.10.1.  Number

        One or two.

       6.10.2.  Arrangement

        No special requirement.

       6.10.3.  Position

       6.10.3.1.  in width: for a single lamp the centre of reference shall be in the median longitudinal plane of the vehicle; or the edge of the illuminating surface which is nearest to that plane shall be not more than 250 mm away from it;

       6.10.3.2.  in height: not less than 250 mm above the ground. No point on the illuminating surface shall be higher than the highest point on the illuminating surface of the passing beam headlamp.

       6.10.3.3.  in length: at the front of the vehicle. This requirement shall be deemed to be satisfied if the light emitted does not cause discomfort to the driver either directly, or indirectly through the rear-view mirrors and/or other reflecting surfaces of the vehicle.

       6.10.4.  Geometric visibility

        Defined by angles alpha and beta as specified in paragraph 2.11.:

        alpha upwards and downwards;

        beta = 45 degrees to left and to right for a single lamp, except for an off-centre light, in which case the inward angle beta = 10 degrees ;

        beta = 45 degrees outwards and 10 degrees inwards for each pair of lamps

       6.10.5.  Orientation

        Forwards. The lamp(s) may move in line with the steering angle.

       6.10.6.  May not be combined with any other front lamp.

       6.10.7.  "Circuit-closed" tell-tale

        Optional; non-flashing green signal.

       6.10.8.  Other requirements

        None.

       6.10.9.  Electrical connections

        It shall be possible to switch the fog lamp(s) on or off independently of the driving beam headlamp(s) and/or passing beam headlamp(s).

       6.11.  REAR FOG LAMP

       6.11.1.  Number

        One or two.

       6.11.2.  Arrangement

        No special requirement.

       6.11.3.  Position

       6.11.3.1.  in height: not less than 250 mm nor more than 900 mm above the ground;

       6.11.3.2.  in length at the rear of the vehicle.

       6.11.3.3.  the distance between the illuminating surface of the rear fog lamp and that of the stop lamp shall not be less than 100 mm.

       6.11.4.  Geometric visibility

        Defined by angles alpha and beta as specified in paragraph 2.11.:

        alpha = 5 degrees upwards and downwards;

        beta = 25 degrees to left and to right for a single lamp 25 degrees outwards and 10 degrees inwards for each pair of lamps.

       6.11.5.  Orientation

        Rearwards.

       6.11.6.  Electrical connections

        They shall be such that the rear fog lamp can light up only when one or more of the following lamps are switched on: driving beam headlamp, passing beam headlamp, front fog lamp.

        If there is a front fog lamp, it shall be possible to
