Until 48 months after the date of entry into force of the 05 series of amendments to this Regulation, no Contracting Party applying this Regulation shall refuse national or regional type approval of a vehicle type approved to the preceding series of amendments to this Regulation. Optional on other eve vehicles.

During replacement, a tell-tale on the dashboard paragraph 2. Arrangement No individual specifications. Figure see paragraph 6. In the case of dipped-beam headlamp, the minimum height in relation to the ground is measured from the lowest f48 of the effective outlet of the optical system e.

Additional sensor functions to improve performance are allowed. The distance between the inner edges of the two apparent surfaces in the direction of the reference axes shall not be less than mm.

The angle of the light beam from the dipped-beam headlamps shall be determined under the following loading conditions.

For vehicles of M and N Categories comments regarding the electrical supply conditions according to Paragraphs 3. If a direction indicator lamp is reciprocally incorporated with a daytime running lamp, the electrical connections of the daytime running lamp on the relevant side of the vehicle shall be such that the daytime running lamp is switched OFF during the entire period both ON and OFF cycle of activation of the direction-indicator lamp.

Some countries have their own national standards for granting type approvals, which may be more stringent than called for by the UN regulations themselves. This lamp is intended, for certain vehicles and trailers, to complement the vehicle’s front and rear position lamps by drawing particular attention to its bulk.

If the vehicle conforms to a vehicle type approved, under one or more other Regulations annexed to the Agreement, in the country which has granted approval under this Regulation, the symbol prescribed in paragraph 4.


Example of a light source with a reflector optic in combination with an area which is not part of this function, behind an outer lens:. They shall be such that the lamp can light up only if the reverse gear is engaged and if the device which controls the starting and stopping of the engine is in such a position that operation of the engine is possible.

One person in the driver’s seat, all the other places in the driving cabin being occupied.

The lighting units for the main-beam may be activated either simultaneously or in pairs. The illuminating surface of the retro-reflector may have parts in common with the apparent surface of any other lamp situated at the rear. For a motor vehicle, when the vehicle is ready to move with its propulsion engine running and its movable components in the normal position s as defined in paragraph 2.

In the case where negative results are recorded, the Type Approval Authority shall ensure that all necessary steps are taken to re-establish the conformity of production as rapidly as possible. Mandatory on motor vehicles having all forward facing lamps with reflectors concealable.

The control for changing over to the dipped beam shall switch off all main-beam headlamps simultaneously. Other means are allowed to obtain a more precise reading for example, removal of the headlamp lens.

All direction-indicator lamps on one side of a vehicle shall be switched on and off by means of one control and shall flash in phase. They do not include tiltable driver cabs of trucks; 2. The following documents, bearing the approval number shown above, are available on request: 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, in the condition defined in paragraphs 2.

Optional on vehicles between 1. However, the technical authorities and manufacturers may jointly propose other methods either experimental or based upon calculationsespecially when the test poses particular problems, provided such calculations are clearly valid.

Angle of geometric visibility 5.

This maximum intensity shall be obtained by adding together the individual reference marks indicated on the several installation units that are simultaneously used to provide the main-beam. Without prejudice to Paragraph 6. Tell me more Already a subscriber. The outer edge of the apparent surface of at least one lighting unit on each side of the vehicle shall not be more than mm from the extreme outer edge of the vehicle A in the figure ; and, The inner edges of the apparent surfaces in the direction of the reference axes shall be not less than mm apart.

In case of a failure of any one of the LED module s producing the principal dipped-beam. The mean value of dipped-beam inclination or vehicle inclination measured with the vehicle in r8 No 1, as defined in Annex 5, for the category of vehicle under test. The lighting functions and modes for r488 the AFS has been approved; 3. Depending on the mounting height in metre h of the lower edge of the apparent surface in the direction of the reference axis of the front fog lamp, measured on the unladen vehicles, the vertical inclination of the cut-off to be set in the unladen vehicle state with one person in the driver’s seat shall have the following value s:.

Regulation 49 – 06 series (click to expand)

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.

These manually adjustable devices shall be ecee from the driver’s seat.

The rear-end collision alert signal shall not be activated if the direction indicator lamps, the sce warning signal or the emergency stop signal is activated. Penalties for non-conformity of production Presence see figure below Mandatory. Rce, one of the most conspicuous differences between UN and US regulations was the design and performance of headlamps. Moreover, the electrical connections of the two optional devices mentioned in paragraph 6. These tests will be on samples selected at random without causing distortion of the manufacturers’ delivery commitments.
