BMW had revealed the M4 Iconic Lights Concept with the interesting Organic Lights technology at the 2015 CES in Las Vegas. The new OLED technology produces light from wafer-thin semiconducting layers of organic material, which have a thickness of just 1.4 millimeters.

In a new video, people behind the project talk about the OLED lighting technology powering the taillights of the M4 Iconic Lights Concept. Here, the characteristic L-shape appears wide and uniformly illuminated; however, in Sports mode, a differently-shaped light pattern can setup by only using some of the OLED segments. The final arrangement then appears as a narrow, sharp “strip” of light.

BMW has confirmed that the Organic Light will debut in a new M car "soon". If that's the case, then we can expect the innovative lighting technology to be equipped in either the upcoming M4 GTS or the all new BMW M2, the M-performance version of the two-door 2-Series.
