In order to determine the CO2 emission reductions that can be attributed to a package of efficient exterior LED lights consisting of an appropriate combination of vehicle lights referred to in Article 1 for the use in M1 non-externally chargeable hybrid electrified vehicles (NOVC-HEVs), it is necessary to establish the following:

3. 
The testing conditions shall fulfil the requirements of Regulation UN/ECE 112 on Uniform provisions concerning the approval of motor vehicle headlamps emitting an asymmetrical passing beam or a driving beam or both and equipped with filament lamps and/or light-emitting diode (LED) modules. The power consumption shall be determined in accordance with point 6.1.4 of Regulation UN/ECE No 112 and points 3.2.1 and 3.2.2 of Annex 10 to that Regulation.

4. 
The following equipment is to be used, as shown in the figure:


— A power supply unit (i.e. variable voltage supplier);
— Two Digital Multi Meters, one for measuring the DC-current, and the other for measuring the DC-voltage. In the figure a possible test set-up is shown, when the DC-voltage meter is integrated in the power supply unit.

5. 
For each efficient exterior LED light included in the package the measurement of the current shall be performed as shown in the figure at a voltage of 13,2 V. LED module(s) operated by an electronic light source control gear, shall be measured as specified by the applicant.

The manufacturer may request that other measurements of the current shall be done at other additional voltages. In that case, the manufacturer must hand over verified documentation on the necessity to perform these other measurements to the type-approval authority. The measurements of the currents at each of those additional voltages are to be performed consecutively at least five (5) times. The exact installed voltages and the measured current is to be recorded in four decimals.

The power consumption has to be determined by multiplying the installed voltage with the measured current. The average of the power consumption for each efficient exterior LED light (PEIi–) has to be calculated. Each value must be expressed in 4 decimals. When a stepper motor or electronic controller is used for the supply of the electricity to the LED lamps, then the electric load of this component part is to be excluded from the measurement.

The resulting power savings of each efficient exterior LED light (ΔPi) are to be calculated with the following formula:
ΔPi=PBi−PEIi–
where the power consumption of the corresponding baseline vehicle light is defined by Table 1.

6. 
The total CO2 savings of the lighting package are to be calculated by Formula 2.
CCO2=∑i=1mΔPi×UFi×t×kCO2VHVop×ηDCDC

The efficiency of the DC-DC converter (ηDCDC) shall be the highest value resulting from the efficiency tests performed in the operative electric current range. The measuring interval shall be equal or lower than 10 % of the operative electric current range.

7. 
The statistical errors in the outcomes of the testing methodology caused by the measurements are to be quantified. For each efficient exterior LED light included in the package the standard deviation is calculated as defined by Formula 4.
SPEIi–=SPEIin=∑j=1nPEIij−PEIi–2nn−1
where:

nNumber of measurements of the sample, which is at least 5

The CO2-emission correction coefficient kCO2 shall be determined from a set of T measurements performed by the manufacturer, as defined in Regulation UN/ECE No 101, Annex 8. For each measurement, the electricity balance during the test and the measured CO2-emissions shall be recorded.

In order to evaluate the statistical error of kCO2, all T combinations without repetitions of T-1 measurements has to be used to extrapolate T different values of kCO2 (i.e. kCO2t). The extrapolation shall be performed according to the method defined in Regulation UN/ECE No 101, Annex 8.

The standard deviation of kCO2SkCO2– is thus calculated as defined by Formula 5.
SkCO2–=SkCO2T=∑t=1TkCO2t−kCO2–2TT−1
where:

TNumber of measurements performed by the manufacturer for the extrapolation of the kCO2 as defined in Regulation UN/ECE No 101, Annex 8kCO2–mean of the T values of kCO2t

The standard deviation of the power consumption of each efficient exterior LED light (SPEIi–) and the standard deviation of the kCO2SkCO2– lead to an error in the CO2 savings (SCCO2). This error is to be calculated by means of Formula 6.

It has to be demonstrated for each type, variant and version of a vehicle fitted with the package of the efficient exterior LED lights that the error in the CO2 savings calculated with Formula 6 is not greater than the difference between the total CO2 savings and the minimum savings threshold specified in Article 9(1) of Implementing Regulation (EU) No 725/2011 (see Formula 7).
MT≤CCO2−SCCO2
where:

MTMinimum threshold [gCO2/km], which is 1 gCO2/km

Where the total CO2 emission savings of the package of the efficient exterior LED lights, as a result of the calculation using Formula 2, and the error in the CO2 savings calculated with Formula 6, are below the threshold specified in Article 9(1) of Implementing Regulation (EU) No 725/2011, the second subparagraph of Article 11(2) of that Regulation shall apply.
