  Scope

  This Regulation applies to front fog lamps for vehicles of categories L3, L4, L5, L7, M, N, and T.[3]

1.  Definitions
 For the purpose of this Regulation,
1.1. The definitions given in Regulation No. 48 and its series of amendments in force at the time of application for type approval shall apply to this Regulation.
1.2. "Lens" means the outermost component of the front fog lamp (unit), which transmits light through the illuminating surface;
1.3. "Coating" means any product or products applied in one or more layers to the outer face of a lens;
1.4.  "Front fog lamps of different types" are front fog lamps that differ in such essential respects as:
1.4.1.  The trade name or mark;
1.4.2.  Different "Classes" (B or F3) identified by particular photometric provisions;
1.4.3.  The characteristics of the optical system; (basic optical design, type / category of light source, LED module, DLS etc.);
1.4.4.  The inclusion of components capable of altering the optical effects by reflection, refraction, absorption and/ or deformation during operation and the variable intensity control, if any;
1.4.5.  The category of filament lamp(s) used, as listed in Regulation No.  37, Regulation No. 99 and/or the LED module or light generator specific identification code (s) (if applicable);
1.4.6.  However, a device intended for the installation on the left side of the vehicle and the corresponding device intended for the installation of the right side of the vehicle shall be considered to be of the same type.
1.5. "Colour of the light emitted from the device". The definitions of the colour of the light emitted, given in Regulation No. 48 and its series of amendments in force at the time of application for type approval, shall apply to this Regulation.
1.6. References made in this Regulation to standard (étalon) light sources and to Regulations Nos. 37 and 99 shall refer to Regulations Nos. 37 and 99 and their series of amendments in force at the time of application for type approval.

2.  Application for approval
2.1. The application for approval shall be submitted by the holder of the trade name or mark or by his duly accredited representative.
2.2. The application relating to each type of front fog lamp shall be accompanied by:
2.2.1. Drawings in triplicate in sufficient detail to permit identification of the type and representing a frontal view of the front fog lamp, with the relevant details of the optical components if any, and the cross-section; the drawings shall indicate the space reserved for the approval mark.
2.2.1.1. If the
