3.10.3. The specific identification code(s) of the additional lighting unit(s). This marking shall be clearly legible and indelible.
This specific identification code shall be comprised of starting letters "ALU" for "Additional Lighting Unit" followed by approval marking without the circle as prescribed in paragraph 4.2.1. below (ex. ALU E43 1234) and in the case where several non-identical additional lighting units are used, additional symbols or characters shall follow (ex. ALU E43 1234-A, ALU E43 1234-B). 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 additional lighting unit(s) is used, but both markings shall be from the same applicant.
