lens may also be used for other types of lamps.
The provisions laid down in paragraph 5.3.2. above are applicable.
5.3.3.1.                        In addition, where the same lens is used, the latter may bear the different approval marks relating to the different types of headlamps or units of lamps, provided that the main body of the lamps, even if it cannot be separated from the lens, also comprises the space described in paragraph 4.4. above and bears the approval marks of the actual functions.
If different types of lamps comprise the same main body, the latter may bear the different approval marks.
5.3.3.2.                        Annex 2, Figure 3, to this Regulation gives examples of arrangements of approval marks relating to the above case.
5.3.4.                              Interdependent lamps as part of an interdependent lamps system
Annex 2, Figure 1a, to this Regulation gives an example of the arrangement of approval marks relating to the above case.
6.                                          General specifications
6.1.                                    Each daytime running lamp shall conform to the specifications set forth in the paragraphs below. An interdependent lamp system shall meet the requirements when all its interdependent lamps are operated together.
6.2.                                    Daytime running lamps shall be so designed and constructed that in normal use, despite the vibration to which they may then be subjected, they continue to function satisfactorily and retain the characteristics prescribed by this Regulation.
6.3.                                    In the case of light source modules, it shall be checked that:
6.3.1.                              The design of the light source module(s) shall be such as:
           (a)   That each light source module can only be fitted in no other position than the designated and correct one and can only be removed with the use of tool(s);
           (b)   If there are more than one light source module used in the housing for a device, light source modules having different characteristics cannot be interchanged within the same lamp housing.
6.3.2.                              The light source module(s) shall be tamperproof.
6.3.3.                              A light source module shall be so designed that regardless of the use of tool(s), it shall not be mechanically interchangeable with any replaceable approved light source.
6.4.                                    Daytime running lamps, which are reciprocally incorporated with another function, using a common light source, and designed to operate permanently with an electronic light source control gear to regulate the intensity of the light emitted, are permitted.
6.5.                                    In the case of replaceable light source(s):
6.5.1.                              Any category or categories of filament lamp(s) approved according to Regulation No. 37 and/or Regulation No. 128 may be used, provided that no restriction on the use is made in Regulation No. 37 and its series of amendments in force at the time of application for type approval or in Regulation No. 128 and its series of
