or outer part (transparent or not) of the device which cannot be separated from the transparent part of the device emitting the light. In any case the marking shall be visible when the device is fitted on the vehicle or when a movable part such as the hood or boot lid or a door is opened.

6.                                          General specifications
6.1.                                    Each side-marker lamp submitted for approval shall conform to the specifications set out in paragraphs 7. and 8. of this Regulation.
6.2.                                    Side-marker lamps shall be so designed and made that, in normal use, despite the vibrations to which they may then be subjected, their satisfactory operation continues to be ensured and they 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 can not 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.                                    In the case of replaceable light source(s):
6.4.1.                              Any category or categories of light source(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 amendments in force at the time of application for type approval.
6.4.2.                              The design of the device shall be such that the light source can be fixed in no other position but the correct one.
6.4.3.                              The light source holder shall conform to the characteristics given in IEC Publication 60061. The holder data sheet relevant to the category of light source used, applies.

7.                                          Intensity of light emitted
7.1.                                    The intensity of the light emitted by each of the two samples submitted shall be:
