# Commission Implementing Decision (EU) 2016/587 of 14 April 2016 on the approval of the technology used in efficient vehicle exterior lighting using light emitting diodes 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cars pursuant to Regulation (EC) No 443/2009 of the European Parliament and of the Council (Text with EEA relevance) (repealed), Division: Formula 3

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

SPEIi–=SPEIin=∑nj=1PEIij−PEIi–2nn−1where:
nNumber of measurements of the sample, which is at least 5
The standard deviation of the power consumption of each efficient exterior LED light (SPEIi–) leads to an error in the CO2 savings (SCCO2). This error is to be calculated by means of Formula 4
