Default BMW brings OLED to tail-lamps

While the laser-headlight concept had already been introduced in the latest M4, where laser was tested as an alternative that threw light precisely and over a distance without the glare of reflectors that would disrupt the oncoming driver's vision, a different more practical concept has been introduced in the rear.

OLED or Organic Light Emitting Diode are known to be much more slimmer, more energy efficient and less ecologically demanding than LED's. The primary difference being that OLED's being organic, do not need a backlighting source. The only disadvantage that OLED's have is that they aren't as bright i.e have less lumens per watt compared to LED's, but this is actually a boon given that the drivers in cars behind do not have to see a red glowing brake-light throwing glare in pitch dark driving conditions, instead there will be a soft yet easily recognisable light with zero glare. Lesser power consumption apart, this would also in time result in smaller & slimmer light fixtures. OLED can also enable sequential-lighting that can activate in a pattern as desired. Since reflectors & clear-glass aren't necessary, I suppose they can also make it out of toughened fibreglass/composite material to make it shatter-resistant.
