Insert new paragraphs 3.5. to 3.7., to read:
"3.5. In the case of an AFS with LED module(s), the corresponding installation unit(s) shall bear the marking of the rated voltage and rated wattage and the light source
module specific identification code.
3.6. LED module(s) submitted along with the approval of the AFS:
3.6.1. Shall bear the trade name or mark of the applicant.  This marking shall be clearly
legible and indelible;
3.6.2. Shall bear the specific identification code of the module. This marking shall be
clearly legible and indelible.
This specific identification code shall comprise the starting letters "MD" for
"MODULE" followed by the approval marking without the circle as prescribed in
paragraph 4.2.1. below and in the case several non identical light source modules are
used, followed by additional symbols or characters.  This specific identification code
shall be shown in the drawings mentioned in paragraph 2.2.1. above.  The approval
marking does not have to be the same as the one on the lamp in which the module is
used, but both markings shall be from the same applicant.
3.7. If an electronic light source control gear which is not part of a LED module is used to
operate a LED module(s), it shall be marked with its specific identification code(s),
the rated input voltage and wattage."
Paragraph 5.3., amend to read:
"5.3.  With the exception of LED modules the system shall not be equipped with light sources that are not approved according to Regulation No. 37 or 99 …." Paragraph 5.9., amend to read:
"5.9. The system shall be so made that, if a light source and/or a LED module has failed, a failure signal in order to comply with the relevant provisions of Regulation
No. 48 shall be provided."
Insert new paragraphs 5.12. to 5.14., to read:
"5.12. The AFS, if equipped with LED modules, and the LED module(s) themselves shall comply with the relevant requirements specified in Annex 11 of this Regulation.
The compliance with the requirements shall be tested.
5.13. In case of an AFS incorporating light sources and/or LED module(s) producing the
basic passing beam and having a total objective luminous flux of the lighting units as
indicated under item 9.3 of the communication form conforming to the model in
Annex 1 which exceeds 2,000 lumen per side a reference shall be made in

LED module(s) shall be measured as described in paragraph    5. of
Annex 11.
5.14. In the case of the basic passing beam in the neutral state being produced exclusively
by LED modules, the total objective luminous flux of these LED modules shall be
equal or greater than 1,000 lumen per side, when measured as described in
paragraph 5. of Annex 11. "
Paragraph 6.2.6.3., amend to read:
"6.2.6.3. When the T-signal corresponds to the vehicle's smallest turn radius to the left (or right), the sum of the illuminance values provided by all contributors of the right or
the left side of the system shall be at least 3 lx at one or more points in the zone
extending from H-H to 2 deg below H-H and from 10 to 45 deg left (or right);" Annex 1
Item 9.2., amend to read:
