annex 1 shall be marked “LED” and with the symbol as indicated in

paragraph 8.3.3.3. The mark “LED” shall be placed after the category

designation separated by a single space, e.g. “PY21W LED”.

2.3.4. Inscriptions other than those covered by paragraphs 2.3.1. and 2.4.4. may be

affixed, on the condition that they do not adversely affect the luminous

characteristics.”

colour temperature* exceeding 3000K and the lighting function is of

another colour than white;

not interfere with the vehicle’s failure-detection equipment and/or

on-board diagnostic systems, if any;

(b) in the case that the LED retrofit light source is located in a

headlamp body above a light source of a rated wattage of 50W or

more and direct air flow is possible from this light source up to the

LED retrofit light source, the hot luminous flux value of the LED

retrofit light source shall not be less than 70% of its objective

luminous flux value at 13.5V DC.

This hot luminous flux value shall be measured determined after 30

still air of a temperature that is equal to the ambient temperature of

the LED retrofit light source installed in the headlamp, when this

headlamp is in still air at a ambient temperature of (23 ± 5) °C and

with both light sources activated.

In the case where doubt exists in respect to the accuracy of the report,

the Authority responsible for type approval may request verification of

the report by testing on the vehicle by a Technical Service.

Screen projection requirements

The following test is intended to define the requirements for the apparent light emitting area

of the LED light source and to determine whether the light emitting area is correctly

positioned relative to the reference axis and reference plane in order to check compliance

with the requirements.

The position of the light emitting area is checked by means of a box system defined in

Figure 2, which shows the projections when viewing along the direction = 0° (top view)

and = 90° (front view) and =180° (bottom view) and = 270° (rear view) in the plane

C0 (C, as defined in Figure 3).

The proportion of the total luminous flux emitted into the viewing direction from the

area(s)

- B shall be 20 per cent or more

- A and C shall each be 15 per cent or more

Normalized luminous intensity distribution

The following test is intended to determine the normalized luminous intensity distribution

of the light source in the C-planes as described in figure 3. The intersection of the reference

axis and the reference plane is used as the coordinate system origin.

The light source is mounted on a flat plate with the corresponding holder features. The plate

is fixed to the goniometer table by a bracket, so that the reference axis of the light source

lines up with one of the rotating axis of the goniometer. The corresponding measurement

set-up is described in figure 3.

Luminous intensity data is recorded with a standard photo-goniometer. The measurement

distance should be chosen appropriately in order to make sure that the detector is located in

the far field of the light distribution.

The measurements shall be performed in C-planes, where C0 shall be the reference plane of

the light source. The C-planes to be measured shall be C0, C30 and C330. The test points for

each plane and multiple polar angles are specified in Table 3.

The measured luminous intensity values, normalised to the measured luminous flux of the

individual light source under test, shall be converted to normalised luminous intensity

values of a 1000 lm light source. These data shall comply with the tolerance band as

defined in Table 3.

temperature of (23 ± 2) °C in still air, whereas LED retrofit light sources shall be measured at an

additional ambient temperature indicated in the relevant light source sheet. For these measurements

the minimum free space as defined in the data sheets shall be maintained.

Light sources of all categories with definition of a temperature Tb shall be measured by stabilising the Tb-

point at the specific temperature defined on the category data sheet.

II. Justification

1. An increasing number of LED retrofit light sources is present in the market, and sold as

replacements for approved light sources.

The public is stimulated by the authorities to use energy efficient lighting like LEDs and is

getting used to LED retrofits in general lighting applications. However, the public is not

aware of and does not understand why automotive LED retrofits in vehicles exterior lamps

bear a safety risk. The public is also not aware that these LED retrofits are not allowed by

many jurisdictions.

On the other hand, there are no legal alternatives for automotive lighting consumers

available, either, nor a way to discriminate the “good” from the “bad”.

2. This is why GTB conducted a feasibility study. GTB reported about the progress of this

study in GRE before and collected feedback; documents GRE-69-41, GRE-70-47, GRE-72-

27 and GRE-73-24.

3. The feasibility study has been finalised and concluded positively. The outcome is reflected

in:

o This proposal to implement provisions into Regulation No. 128, including:

o New category sheets C5W, PY21W and R5W in LED technology;

o Equivalence criteria to guide specifying sheets for LED retrofit light source

categories. These guidelines are intended for publication, with the agreement of

GRE, in the GRE website for “reference documents”, similar to criteria for new

filament light sources for head lighting; document GRE-74-[xx];

o Equivalence reports for the new categories C5W, PY21W and R5W in LED

technology; GRE-74-[xx];

4. As for other light sources is the case, additional tests on voluntary basis are described in

standards as from IEC or SAE.

5. GTB is requesting for advice from Contracting Parties on possible issues related to national

law and possible other legal issues that might arise when introducing approved LED retrofit

light sources.

6. The relevant parts of this proposal can easily be merged with the proposals for

simplification of light source regulations.
