5. GENERAL SPECIFICATIONS
5.1. The lighting and light-signalling devices shall be so fitted that in normal conditions of use,
and notwithstanding the vibrations to which they may be subjected, they retain the
characteristics prescribed by the Regulation and enable the vehicle to comply with the
requirements of this Regulation.
In particular, it shall not be possible for the lamps to be inadvertently maladjusted.
5.2. The illuminating lamps shall be so installed that correct adjustment of their orientation can
easily be carried out.
5.3. For all light-signalling devices the reference axis of the lamp when fitted to the vehicle shall
be parallel to the bearing plane of the vehicle on the road; in addition, it shall be
perpendicular to the median longitudinal plane of the vehicle in the case of side
retro-reflectors and parallel to that plane in the case of all light-signalling devices. A
tolerance of ±3° shall be allowed in each direction. In addition, if specifications for fitting are
provided by the manufacturer they shall be complied with.
5.4. In the absence of specific instructions, the height and orientation of the lamps shall be
verified with the vehicle unladen and placed on a flat horizontal surface, its median
longitudinal plane being vertical and the handlebars being in the position corresponding to
the straight ahead movement. The tyre pressures shall be those prescribed by the
manufacturer for the particular conditions of loading required in this Regulation.
5.5. In the absence of specific instructions:
5.5.1. Single lamps or reflectors shall be mounted such that their centre of reference lies in the
median longitudinal plane of the vehicle;

measured from the lowest point of the effective outlet of the optical system (e.g. reflector,
lens, projection lens) independent of its utilisation.
Where the (maximum and minimum) height above the ground clearly meets the
requirements of the Regulation, the exact edges of any surface need not be determined.
When referring to the distance between lamps, the position, as regards width, shall be
determined from the inner edges of the apparent surface in the direction of the reference
axis.
Where the position, as regards width, clearly meets the requirements of the Regulation, the
exact edges of any surface need not be determined.
For the purposes of reducing the geometric visibility angles, the position of a lamp with
regard to height above the ground, shall be measured from the H Plane.

And when the test vehicle is returned to the position as specified in Paragraph 5.4., the
HIAS test angle shall return to zero quickly.
The handlebar may be fixed in the straight ahead position so as not to move during the
vehicle inclination.
For the test the HIAS shall be activated by means of an HIAS signal generator.
The system shall be considered to satisfy the requirements of Paragraph 6.2.5.5. above, if

lighting is activated. The bank angles to measure are the bank angles specified by the
manufacturer during type approval of the device according to Regulation No. 113.
The handlebar may be fixed in the straight ahead position so as not to move during the
vehicle inclination.
For the test, the bend lighting may be activated by means of a signal generator provided by
the manufacturer.
The system is considered to satisfy the requirements of Paragraph 6.2.5.7. above, if all
measured bank angles on both sides of the vehicle are greater than or equal to the
minimum bank angles given in the communication form for the type approval of the device

Re-position the passing beam so that its horizontal and vertical alignments are the
same as a headlamp not equipped with HIAS.
The manufacturer shall provide a detailed description of the procedure for resetting the
HIAS.
Alternatively, the manufacturer may choose to install an automatic system that either
achieves both tasks specified above or resets the HIAS. In this case, the manufacture shall
provide the test house with a description of the automatic system and, until such time as
