The requirements pertinent to each lamp and to the category/ies of vehicle on which the lamp is intended to be installed shall be applied, where its verification at the moment of lamp type approval is feasible.
a7c0
5.1. Each sample shall comply with the specifications set forth in paragraphs 6. to 8. below. a0c0
5.2. Headlamps shall be so made as to retain their prescribed photometric characteristics and to remain in good working order when in normal use, in spite of the vibrations to which they may be subjected. a0c0
5.2.1. Headlamps shall be fitted with a device enabling them to be so adjusted on the vehicle as to comply with the rules applicable to them. Such a device need not be fitted on units in which the reflector and the diffusing lens cannot be separated, provided the use of such units is confined to vehicles on which the headlamps setting can be adjusted by other means. a0c0

5.3. Headlamps designed to satisfy the requirements of both right-hand and of left-hand traffic may be adapted for traffic on a given side of the road either by an appropriate initial setting when fitted on the vehicle or by selective setting by the user.

In all cases, only two different and clearly distinct settings, one for right-hand and one for left-hand traffic, shall be possible, and the design shall preclude inadvertent shifting from one setting to the other or setting in an intermediate position. Where two different setting positions are provided for the light source, the components for attaching the light source to the reflector must be so designed and made that, in each of its two settings, the light source will be held in position with the precision required for headlamps designed for traffic on only one side of the road.

5.4.1. In the case of headlamps designed to meet the requirements of traffic moving on one side of the road (either right or left) only, appropriate measures shall be taken to prevent discomfort to road-users in a country where traffic moves on the side of the road opposite to that of the country for which the headlamp was designed[6]. Such measures may be: a0c0
[6] Instructions on the installation of lamps fitted with these measures are given in Regulation No. 48. a0c0

5.5. On headlamps designed to provide alternately a driving beam and a passing beam or a passing beam and/or a driving beam designed to become a bend lighting, any mechanical, electro-mechanical or other device incorporated in the headlamp for these purposes[7] must be so constructed that: a0c0
[7] These provisions shall not apply to the control switch. a0c0
5.5.1. The device is robust enough to withstand 50,000 operations under normal conditions of use. In order to verify compliance with this requirement, the Technical Service responsible for approval tests may: a0c0
... (a) Require the applicant to supply the equipment necessary to perform the test; a0c0
... (b) Forego the test if the headlamp presented by the applicant is accompanied by a test report, issued by a Technical Service responsible for approval tests for headlamps of the same construction (assembly), confirming compliance with this requirement. a0c0
5.5.2. In the case of failure the luminous intensity of the headlamp above the line H-H shall not exceed the values of a passing beam according to paragraph 6.2.6.; in addition, on headlamps designed to provide a passing and/or a driving beam to become a bend lighting, a luminous intensity of at least 2,500 cd shall be fulfilled in test point 25 V (VV line, 1.72 D). a0c0
5.5.3. Either the principal passing beam or the driving beam can always be obtained without any possibility of the mechanism stopping in between the two positions; a0c0
5.5.4. The user cannot, with ordinary tools, change the shape or position of the moving parts. a0c0
5.6. Complementary tests shall be done according to the requirements of Annex 4 to ensure that in use there is no excessive change in photometric performance. a0c0

A10  Moving upward from below the line B (see figure 2 below), a vertical scan is carried out through the horizontal part of the "cut-off" at 2.5° from V-V. The inflection point (where d2 (log E) / dv2 = 0) is determined and positioned on the line B situated one per cent below H-H. a0c0
A10 3.2. Horizontal adjustment a0c0
A10  The applicant shall specify one of the following horizontal aim methods: a0c0
A10  a)The "0.2 D line" method (see figure 2 below). a0c0
A10  A single horizontal line at 0.2° D shall be scanned from 5° left to 5° right after the lamp has been aimed vertically. The maximum gradient "G" determined using the formula G = (log Eβ – log E(β + 0.1°)) where β is the horizontal position in degrees, shall not be less than 0.08. a0c0
