size of the components of a single approval mark shall not be less than the minimum size required for the smallest of the individual marks by a Regulation under which approval has been granted.
4.4.4.                              An approval number shall be assigned to each type approved. The same Contracting Party may not assign the same number to another type of grouped, combined or reciprocally incorporated lamps covered by this Regulation.
4.5.                                    The mark and symbol referred to in paragraphs 4.3.1. and 4.3.2. shall be indelible and shall be clearly legible even when the cornering lamp is mounted on the vehicle.
4.6.                                    Annex 2 gives examples of approval marks for a single lamp (Figure 1) and for grouped, combined or reciprocally incorporated lamps (Figure 2) with all the additional symbols referred to above, in which the letter "K" indicates a cornering lamp.
4.7.                                    The approval marking shall be clearly legible and indelible. It may be placed on an inner 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.
5.                                          General specifications
5.1.                                    Each sample shall conform to the specifications set forth in the paragraphs below.
5.2.                                    Cornering 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.
5.3.                                    In the case of light source modules, it shall be checked that:
5.3.1.                              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.
5.3.2.                              The light source module(s) shall be tamperproof.
5.3.3.                              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.
5.4.                                    In the case of replaceable light sources:
5.4.1.                              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
