Determination of the power savings
2.2.1.
Measurement of the power consumption
For each efficient exterior LED light included in a combination, the measurement of the current shall be performed 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 additional measurements of the current shall be performed at other voltages, where the necessity to do so can be demonstrated on the basis of verified documentation.
In any case the measurements (n) shall be performed for each voltage at least five times consecutively. The applied voltage and the measured current shall be recorded in four decimals.
The power consumption shall be determined by multiplying the voltage with the measured current. The average of the power consumption for each efficient exterior LED light [W] shall be calculated as set out in Formula 1 with four decimals to be taken into account in the calculations. 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 is to be excluded from the measurement.
Formula 1
where:
is the tested voltage of each LED vehicle light i [V]
is the measured current of each LED vehicle light i [A]
n
is the number of measurements of the sample
j
refers to an individual measurement of power consumption
In case of low beam AFS, the power consumption [W] shall be calculated as the average of the LED power consumption for each class k, weighted according to the WLTP time share per speed range, in accordance with Formula 2.
Formula 2
where:
is the power consumption at the LED intensity for each class k as the average of n consecutive measurements [W]
K
is the number of classes associated with the low beam AFS.
WLTP_share is the WLTP time share per speed range in each class as defined in Table 2.

When the low beam AFS does not fall within all four classes specified in Table 1, the WLTP_share of the missing classes shall be attributed to class C.
2.2.2.
Calculation of the power savings
The power savings of each efficient exterior LED light (ΔP i ) [W] shall be calculated in accordance with Formula 3.

The type-approval authority shall ensure for each version of a vehicle fitted with the efficient exterior LED lights that the minimum threshold criterion as specified in Article 9(1)(b) of Implementing Regulation (EU) No 427/2014 is met.
When verifying whether the minimum threshold criterion is met, the type-approval authority shall take into account, in accordance with Formula 9, the CO 2 savings determined in point 3 and the uncertainty determined in point 4.
Formula 9
where:
MT
is the minimum threshold equal to 0,5 g CO 2 /km

7. CERTIFICATION OF THE CO 2 SAVINGS
The CO 2 savings to be certified by the type-approval authority in accordance with Article 11 of Implementing Regulation (EU) No 427/2014 [g CO 2 /km] are those calculated in accordance with Formula 10.
The CO 2 savings shall be recorded in the type approval certificate for each vehicle version fitted with the efficient exterior LED lights.
Formula 10
