Lamp reciprocally incorporated with a headlamp

Figure 3

The above example corresponds to the marking of a lens intended to be used in different types of headlamps, namely:

either:

a headlamp with a passing beam designed for right-hand and left-hand traffic and a driving beam with a maximum intensity comprised between 86,250 and 101,250 candelas, approved in Germany (E1) in accordance with the requirements of Regulation No. 8 as amended by the 04 series of amendments; which is reciprocally incorporated with a front direction indicator approved in accordance with the 01 series of amendments to Regulation No. 6;

or:

a headlamp with a passing beam designed for right-hand and left-hand traffic and a driving beam, approved in Germany (E1) in accordance with the requirements of Regulation No. 1 as amended by the 01 series of amendments, which is reciprocally incorporated with the same front direction indicator as above; or even:   either of the above-mentioned headlamps approved as a single lamp.

The main body of the headlamp shall bear the only valid approval number, for instance:

PHOTOMETRIC MEASUREMENTS

       1. Measurement methods

       1.1. During photometric measurements, stray reflections shall be avoided by appropriate masking.

       1.2. In case the results of measurements should be challenged, measurements shall be carried out in such a way as to meet the following requirements:

       1.2.1. The distance of measurement shall be such that the law of the inverse of the square of the distance is applicable;

       1.2.2. The measuring equipment shall be such that the angular aperture of the receiver viewed from the reference centre of the light is comprised between 10' and 1 degree;

       1.2.3. The intensity requirement for a particular direction of observation shall be deemed to be satisfied if that requirement is met in a direction deviating by not more than one - quarter of a degree from the direction of observation.

       2. Table  of  standard  light  distribution  in  space  for  direction  indicators  of  the categories 1, 1 a. 1 b, 2a, 2b 3. 4 and 5

       For direction indicators of category 6

       2.1. The direction H = 0 degrees and V = 0 degrees  corresponds to the reference axis. (On the vehicle, it is horizontal, parallel to the median longitudinal plane of the vehicle and oriented in the required direction of visibility.) It passes through the centre of reference. The values shown in the tables give, for the various directions of measurement, the minimum intensities as a percentage of the minimum intensities required in the table in paragraph 6.1.:

       2.1.1. in the direction H = 0 degrees  and V = 0 degrees  for categories 1, 1a, 1b, 2a, 2b, 3 and in the case of
