Headlamps designed to satisfy the requirements both of right hand and of left hand traffic may be adapted for traffic on a given side of the road either by an appropriate initial setting when fitted on the vehicle or by selective setting by the user. Such initial or selective setting may consist, for example, of fixing either the optical unit at a given angle on the vehicle or the filament lamp or LED module(s) producing the principal passing-beam at a given angle/position in relation to the optical unit. In all cases, only two different and clearly distinct settings, one for right hand and one for left-hand traffic, shall be possible, and the design shall preclude inadvertent shifting from one setting to the other or setting in an intermediate position. Where two different setting positions are provided for the filament lamp or LED module(s) producing the principal passing-beam, the components for attaching the filament lamp or LED module(s) producing the principal passing-beam to the reflector must be so designed and made that, in each of its two settings, this filament lamp or LED module(s) will be held in position with the precision required for headlamps designed for traffic on only one side of the road. Conformity with the requirements of this paragraph shall be verified by visual inspection and, where necessary, by a test fitting. a0c0
5.5. Complementary tests shall be done according to the requirements of Annex 4 to ensure that in use there is no excessive change in photometric performance. a0c0

6.1. General provisions a0c0
6.1.1. Headlamps shall be so made that they give adequate illumination without dazzle when emitting the passing-beam, and good illumination when emitting the driving-beam. Bend lighting may be produced by activating one additional filament light source or one or more LED module(s) being part of the passing-beam headlamp. a0c0
6.1.2.

The luminous intensity produced by the headlamp shall be measured at 25 m distance by means of a photoelectric cell having a useful area comprised within a square of 65 mm side. The point HV is the centre-point of the coordinate system with a vertical polar axis. Line h is the horizontal through HV (see Annex 3 to this Regulation).

 a0c0
6.1.3.

Apart from LED module(s), the headlamps shall be checked by means of an uncoloured standard (étalon) filament lamp designed for a rated voltage of 12 V.

 a0c0
6.1.3.1.

During the checking of the headlamp, the voltage at the terminals of the filament lamp shall be regulated as to obtain the reference luminous flux at 13.2 V as indicated for each filament lamp at the relevant data sheet of Regulation No. 37.

 a0c0
...

However, if a filament lamp of category H9 or H9B is used for the principal passing-beam, the applicant may choose the reference luminous flux at 12.2 V or 13.2 V as indicated in the relevant data sheet of Regulation No. 37 and a reference stating which voltage was chosen for type approval shall be made in item 9 in the communication form of Annex 1.

 a0c0
6.1.3.2.

In order to protect the standard (étalon) filament lamp during the process of photometric measurement it is permissible to carry out the measurements at a luminous flux that differs from the reference luminous flux at 13.2 V. If the Technical Service chooses to carry out measurements in such a manner, the luminous intensity shall be corrected by multiplying the measured value by the individual factor F lamp of the standard (étalon) filament lamp in order to verify the compliance with the photometric requirements where:

 a0c0
... F lamp = Φ reference / Φ test a0c0
...

Φ reference is the reference luminous flux at 13,2 V as specified in the relevant data sheet of Regulation No. 37

 a0c0
... Φ test is the actual luminous flux used for the measurement. a0c0
...

However, where the reference luminous flux of 12.2 V as specified in the data sheet for the category H9 or H9B is chosen, this procedure is not permitted.

 a0c0
6.1.3.3.

The headlamp shall be considered acceptable if it meets the requirements of paragraph 6. with at least one standard (étalon) filament lamp, which may be submitted with the headlamp.

 a0c0
6.1.4.

LED module(s) shall be measured at 6.3 V, 13.2 V or 28.0 V respectively, if not otherwise specified within this Regulation. LED module(s) operated by an electronic light source control gear, shall be measured as specified by the applicant.

 a0c0
6.1.5. In the case of headlamps equipped with LED module(s) and filament lamps, the part of the headlamp with filament lamp(s) shall be tested according to paragraph 6.1.3. and the part of the headlamp with LED module(s) shall be evaluated according to the provisions of paragraph 6.1.4. and then added to the previous result obtained from the filament lamp(s) tested. a0c0
6.2. Provisions concerning passing-beams a0c0
6.2.1. The luminous intensity distribution of the principal passing-beam headlamp shall incorporate a "cut-off" (see Figure 1), which enables the headlamp to be adjusted correctly for the photometric measurements and for the aiming on the vehicle. a0c0
... The "cut-off" shall provide: a0c0
... (a)For right hand traffic beams: a0c0
... (i)A straight "horizontal part" towards the left; a0c0
... (ii)A raised "elbow - shoulder" part towards the right. a0c0
... (b)For left hand traffic beams: a0c0
... (i)A straight "horizontal part" towards the right; a0c0
... (ii)A raised "elbow - shoulder" part towards the left. a0c0
... In each case the "elbow-shoulder" part shall have a sharp edge. a0c0
6.2.2.

The headlamp shall be visually aimed by means of the "cut-off" (see Figure 1) as follows. The aiming shall be carried out using a flat vertical screen set up at a distance of 10 m or 25 m (as indicated in item 9 of Annex 1) forward of the headlamp and at right angles to the H-V axis as shown in Annex 3 to this Regulation. The screen shall be sufficiently wide to allow examination and adjustment of the "cut-off" of the passing-beam over at least 5° on either side of the V-V line.

 a0c0
6.2.2.1.

For vertical adjustment: the horizontal part of the "cut-off" is moved upward from below line B and adjusted to its nominal position one per cent (0.57 degrees) below the H-H line;

 a0c0
... Figure 1 a0c0
... a0c0
... Note: The scales are different for vertical and horizontal lines. a0c0
6.2.2.2.

For horizontal adjustment: the "elbow - shoulder" part of the "cut-off" shall be moved:

 a0c0
... For right hand traffic from right to left and shall be horizontally positioned after its movement so that: a0c0
...

(a)Above the line 0.2° D its "shoulder" shall not exceed the line A to the left;

 a0c0
...

(b)The line 0.2° D or below its "shoulder" should cross the line A; and

 a0c0
... (c)The kink of the "elbow" is basically located within +/-0.5 degrees to the left or right of the V-V line; a0c0
... or a0c0
... For left hand traffic from left to right and shall be horizontally positioned after its movement so that: a0c0
... (a)Above the line 0.2 D its "shoulder" shall not exceed the line A to the right; a0c0
...

(b)On the line 0.2° or below its "shoulder" cross the line A; and

 a0c0
... (c)The kink of the "elbow" should be primarily on the V-V line; a0c0
6.2.2.3. Where a headlamp so aimed does not meet the requirements set out in paragraphs 6.2.4. to 6.2.6. and 6.3., its alignment may be changed, provided that the axis of the beam is not displaced: a0c0
... Horizontally from line A by more than: a0c0
...

(a) 0.5° to the left or 0.75° to the right, for right hand traffic; or

 a0c0
...

(b)0.5° to the right or 0.75° to the left, for left hand traffic; and

 a0c0
...

Vertically not more than 0.25° up or down from line B.

 a0c0
6.2.2.4. If, however, vertical adjustment cannot be performed repeatedly to the required position within the tolerances described in paragraph 6.2.2.3. above, the instrumental method of Annex 9, paragraphs 2. and 3. shall be applied to test compliance with the required minimum quality of the "cut-off" and to perform the vertical and horizontal adjustment of the beam. a0c0
6.2.3. When so aimed, the headlamp, if its approval is sought solely for provision of a passing-beam[8], need comply only with the requirements set out in paragraphs 6.2.4. to 6.2.6. below; if it is intended to provide both a passing-beam and a driving-beam, it shall comply with the requirements set out in paragraphs 6.2.4. to 6.2.6. and 6.3. a0c0
[8] Such a special "passing-beam" headlamp may incorporate a driving-beam not subject to requirements. a0c0
6.2.4. The passing-beam shall meet the luminous intensities at the test points referred to in the tables below and in Annex 3 Figure B (or mirrored about the VV line for left-hand traffic): a0c0
... a0c0
... a0c0
... a0c0
6.2.5. There shall be no lateral variations detrimental to good visibility in any of the zones I, II, III and IV. a0c0
6.2.6. Headlamps designed to meet the requirements of both right-hand and left-hand traffic must, in each of the two setting positions of the optical unit or LED module(s) producing the principal passing-beam or of the filament lamp, meet the requirements set forth above for the corresponding direction of traffic. a0c0
6.2.7.

The requirements in paragraph 6.2.4. above shall also apply to headlamps designed to provide bend lighting and/or that include the additional light source or LED module(s) referred to in paragraph 6.2.8.2. In the case of a headlamp designed to provide bend lighting its alignment may be changed, provided that the axis of the beam is not displaced vertically by more than 0.2°.

 a0c0
6.2.7.1. If bend lighting is obtained by: a0c0
6.2.7.1.1. Swivelling the passing-beam or moving horizontally the kink of the elbow of the cut-off, the measurements shall be carried out after the complete headlamp assembly has been reaimed horizontally, e.g. by means of a goniometer; a0c0
6.2.7.1.2. Moving one or more optical parts of the headlamp without moving horizontally the kink of the elbow of the cut-off, measurements shall be carried out with these parts being in their extreme operating position; a0c0
6.2.7.1.3. Means of one additional filament light source or one or more LED module(s) without moving horizontally the kink of the elbow of the cut-off, measurements shall be carried out with this light source or LED module(s) activated. a0c0
6.2.8. Only one filament light source or one or more LED module(s) are permitted for the principal passing-beam. Additional light sources or LED modules are permitted only as follows (see Annex 10): a0c0
6.2.8.1. One additional light source according to Regulation No. 37 or one or more additional LED module(s) may be used inside the passing-beam headlamp to contribute to bend lighting; a0c0
6.2.8.2. One additional light source according to Regulation No. 37 and/or one or more LED module(s), inside the passing-beam headlamp, may be used for the purposes of generating infrared radiation. It/they shall only be activated at the same time as the principal light source or LED module(s). In the event that the principal light source or (one of) the principal LED module(s) fails, this additional light source and/or LED module(s) shall be automatically switched off; a0c0
6.2.8.3. In the event of failure of an additional filament light source or one or more additional LED module(s), the headlamp shall continue to fulfil the requirements of the passing-beam. a0c0
6.3. Provisions concerning driving-beams a0c0
6.3.1.

In the case of a headlamp designed to provide a driving-beam and a passing-beam, measurements of the luminous intensity of the driving-beam shall be taken with the same headlamp alignment as for measurements under paragraphs 6.2.4. to 6.2.6. above; in the case of a headlamp providing a driving-beam only, it shall be so adjusted that the area of maximum luminous intensity is centred on the point of intersection of lines H-H and V-V; such a headlamp need meet only the requirements referred to in paragraph 6.3. Where more than one light source is used to provide the driving-beam, the combined functions shall be used to determine the maximum value of the luminous intensity (IM).

 a0c0
6.3.2. Irrespective of the type of light source (LED module(s) or filament light source(s)) used to produce the principal passing-beam, several light sources: a0c0
... (a)Either filament light sources listed in Regulation No. 37; or a0c0
... (b)LED module(s) may be used for each individual driving-beam. a0c0
6.3.3. Referring to Annex 3, Figure C and the table below, the luminous intensity distribution of the driving-beam shall meet the following requirements: a0c0
... a0c0
6.3.3.1.

The point of intersection (HV) of lines h h and v v shall be situated within the isolux 80 per cent of maximum luminous intensity (Imax)

 a0c0
6.3.3.2. The maximum value (IM) shall in no circumstances exceed 215,000 cd. a0c0
6.3.4.

The reference mark (I'M) of the maximum luminous intensity, referred to in paragraph 6.3.3.2. above, shall be obtained by the ratio:

 a0c0
... I'M = IM /4,300 a0c0
... This value shall be rounded off to the value 7.5 - 10 - 12.5 - 17.5 - 20 - 25 - 27.5 - 30 - 37.5 - 40 - 45 - 50. a0c0
6.4. In the case of headlamps with adjustable reflector the requirements of paragraphs 6.2. and 6.3. are applicable for each mounting position indicated according to paragraph 2.1.3. For verification the following procedure shall be used: a0c0
6.4.1. Each applied position is realized on the test goniometer with respect to a line joining the centre of the light source and point HV on a aiming screen. The adjustable reflector is then moved into such a position that the light pattern on the screen corresponds to the aiming prescriptions of paragraphs 6.2.1. to 6.2.2.3. and/or 6.3.1.; a0c0
6.4.2. With the reflector initially fixed according to paragraph 6.4.1., the headlamp must meet the relevant photometric requirements of paragraphs 6.2. and 6.3.; a0c0
6.4.3.

Additional tests are made after the reflector has been moved vertically ±2° or at least into the maximum position, if less than 2°, from its initial position by means of the headlamps adjusting device. Having re-aimed the headlamp as a whole (by means of the goniometer for example) in the corresponding opposite direction the light output in the following directions shall be controlled and lie within the required limits:

 a4c0
... Passing-beam: points B50L and 75 R (B50R and 75 L, respectively); a4c0
... Driving-beam: IM and point HV (percentage of IM). a4c0
6.4.4. If the applicant has not indicated more than one mounting position, the procedure of paragraphs 6.4.1. to 6.4.3. shall be repeated for all other positions; a0c0
6.4.5.

If the applicant has not asked for special mounting positions, the headlamp shall be aimed for measurements of paragraphs 6.2. and 6.3. with the headlamps adjusting device in its mean position. The additional test of paragraph 6.4.3. shall be made with the reflector moved into its extreme positions (instead of ±2°) by means of the headlamps adjusting device.

 a0c0
7. Colour a0c0
7.1. The colour of the light emitted shall be white. a0c0
8. Gauging of discomfort a0c0
... The discomfort caused by the passing-beam of headlamps shall be gauged[9]. a0c0
[9] This requirement will be the subject of a recommendation to administrations. a0c0
C. Further administrative provisions a0c0
9. Modification of the headlamp type and extension of approval a0c0
9.1. Every modification of the headlamp type shall be notified to the Type Approval Authority which approved the headlamp type. The said Authority may then either: a0c0
9.1.1. Consider that the modifications made are unlikely to have appreciable adverse effects and that in any event the headlamp still complies with the requirements; or a0c0
9.1.2. Require a further test report from the Technical Service responsible for conducting the tests. a0c0

A6  Equipment (see Figure 1 below) a0c0
A6 

The beam of a collimator K with a half divergence β /2 = 17.4 x 10-4 rad is limited by a diaphragm D τ with an opening of 6 mm against which the sample stand is placed.

 a0c0
A6

 a0c0
A6 

An annular diaphragm DD, with angles a0/2 = 1 deg and amax/2 = 12 degrees is placed in an image focal plane of the lens L2.

 a0c0
A6  The non-transparent central part of the diaphragm is necessary in order to eliminate the light arriving directly from the light source. It shall be possible to remove the central part of the diaphragm from the light beam in such a manner that it returns exactly to its original position. a0c0
A6  The distance L2 Dτ and the focal length F2 of the lens L2 shall be so chosen that the image of Dτ completely covers the receiver R. a0c0

A9 

Before carrying out the measurement of the quality of "cut-off" and the instrumental aiming procedure, a visual pre-aim in accordance with paragraphs 6.2.2.1. and 6.2.2.2. of this Regulation is required.

 a0c0
A9 2. Measurement of the quality of the "cut-off" a0c0
A9 

To determine the minimum sharpness, measurements shall be performed by vertically scanning through the horizontal part of the "cut-off" in angular steps of 0.05  at either a measurement distance of:

 a0c0
A9  (a)10 m with a detector having a diameter of approximately 10 mm or a0c0

A9 

The measuring distance at which the test was carried out shall be recorded in item 9. of the communication form (see Annex 1 of this Regulation).

 a0c0
A9 

To determine the maximum sharpness, measurements shall be performed by vertically scanning through the horizontal part of the "cut-off" in angular steps of 0.05° exclusively at a measurement distance of 25 m and with a detector having a diameter of approximately 30 mm.

 a0c0

The sharpness factor G is determined by scanning vertically through the horizontal part of the "cut-off" at 2.5° from the V-V where:

 a0c0
A9 

G = (log Eβ - log E(β + 0.1°)) where β = the vertical position in degrees.

 a0c0
A9  The value of G shall not be less than 0.13 (minimum sharpness) and not greater than 0.40 (maximum sharpness). a0c0

The part of the horizontal "cut-off" that serves for vertical adjustment shall be horizontal between 1.5° and 3.5° from the V-V line (see Figure 1).

 a0c0
A9 

The inflection points of the "cut-off" gradient at the vertical lines at 1.5°, 2.5° and 3.5° shall be determined by the equation:

 a0c0
A9 

The maximum vertical distance between the inflection points determined shall not exceed 0.2°.

 a0c0
A9  (d2 (log E) / dβ2 = 0). a0c0

A9  Note: The scales are different for vertical and horizontal lines. a0c0
A9 3.1. Vertical adjustment a0c0
A9 

Moving upward from below the line B (see Figure 2 below), a vertical scan is carried out through the horizontal part of the "cut-off" at 2.5° from V-V. The inflection point (where d2 (log E) / dv2 = 0) is determined and positioned on the line B situated one per cent below H-H.

 a0c0
A9 3.2. Horizontal adjustment a0c0
A9  The applicant shall specify one of the following horizontal aim methods: a0c0
A9  (a)The "0.2 D line" method (see Figure 2 below). a0c0
A9 

A single horizontal line at 0.2° D shall be scanned from 5° left to 5° right after the lamp has been aimed vertically. The maximum gradient "G" determined using the formula G = (log Eβ - log E(β + 0.1°)) where β is the horizontal position in degrees, shall not be less than 0.08.

 a0c0
A9 

The inflection point found on the 0.2 D line shall be positioned on the line A.

A9 

Three vertical lines shall be scanned from 2° D to 2° U at 1°R, 2°R, and 3°R after the lamp has been aimed vertically. The respective maximum gradients "G" determined using the formula:

 a0c0
A9 

G = (log Eβ ± log E(β + 0.1°))

 a0c0
A9  where β is the vertical position in degrees, shall not be less than 0.08. The inflection points found on the three lines shall be used to derive a straight line. The intersection of this line and the line B found while performing vertical aim shall be placed on the V line. a0c0

A10 4.3.1. Illuminance a0c0
A10 4.3.1.1. A photometric measurement of the headlamp shall be made after 1 minute of operation for the specific function at the test point specified below. For these measurements, the aim can be approximate but must be maintained for before and after ratio measurements. a1c0
A10  Test points to be measured: a1c0
A10  Passing-beam 25 R a1c0
A10  Driving-beam HV a1c0
A10 4.3.1.2.

The lamp shall continue operation until photometric stability has occurred. The moment at which the photometry is stable is defined as the point in time at which the variation of the photometric value is less than 3 per cent within any 15 minutes period. After stability has occurred, aim for complete photometry shall be performed in accordance with the requirements of the specific device. Photometer the lamp at all test points required for the specific device.

A10 4.3.1.3.

Calculate the ratio between the photometric test point value determined in paragraph 4.3.1.1. above and the point value determined in paragraph 4.3.1.2. above.

 a0c0
A10 4.3.1.4. Once stability of photometry has been achieved, apply the ratio calculated above to each of the remainder of the test points to create a new photometric table that describes the complete photometry based on one minute of operation. a0c0
A10 4.3.1.5. The luminous intensity values, measured after one minute and after photometric stability has occurred, shall comply with the minimum and maximum requirements. a0c0
A10 4.3.2. Colour a0c0
A10 

The colour of the light emitted measured after one minute and measured after photometric stability has been obtained, as described in paragraph 4.3.1.2. of this annex, shall both be within the required colour boundaries.

A10 5. The measurement of the objective luminous flux of LED module(s) producing the principal passing-beam shall be carried out as follows: a0c0
A10 5.1. The LED module(s) shall be in the configuration as described in the technical specification as defined in paragraph 2.2.2. of this Regulation. Optical elements (secondary optics) shall be removed by the Technical Service at the request of the applicant by the use of tools. This procedure and the conditions during the measurements as described below shall be described in the test report. a0c0
A10 5.2. One module of each type shall be submitted by the applicant with the light source control gear, if applicable, and sufficient instructions. a3c0
A10  Suitable thermal management (e.g. heat sink) may be provided, to simulate similar thermal conditions as in the corresponding headlamp application. a3c0
A10  Before the test the LED module shall be aged at least for seventy-two hours under the same conditions as in the corresponding headlamp application. a3c0
A10 

In the case of use of an integrating sphere, the sphere shall have a minimum diameter of one meter, and at least ten times the maximum dimension of the LED module, whichever is the largest. The flux measurements can also be performed by integration using a goniophotometer. The prescriptions in CIE -Publication 84 - 1989, regarding the room temperature, positioning, etc., shall be taken into consideration.

 a3c0
A10  The LED module shall be burned in for approximately one hour in the closed sphere or goniophotometer. a3c0
