# Commission Implementing Decision of 13 March 2013 on the approval of the use of light emitting diodes in certain lighting functions of an M1 vehicle as an innovative technology for reducing CO2 emissions from passenger cars pursuant to Regulation (EC) No 443/2009 of the European Parliament and of the Council (Text with EEA relevance) (2013/128/EU), Division 2: DETERMINATION OF THE ELECTRIC POWER CONSUMPTION OF THE LEDS

Extent: E+W+S+N.I.

The electric power consumption of the LEDs for each of the lighting functions concerned is to be determined as the multiplication of the battery voltage and the electric current of each lighting unit with the number of lights of each lighting unit, according to the formula:
PLED = U × I × n ;
PLED electric power consumption of an LED lighting function (W);
U battery voltage (V) This value can be measured with a multimeter;
I electric current (A). This value can be measured with a multimeter;
n number of lights in function.
The measurement of the power consumption of the LEDs may be done separate from the NEDC hot test (see point 4 of this Annex).
