These technologies will be shown on a new concept car that BMW will unveil during the show.
Laser light may sound like a dangerous technology for headlights, but it's actually more efficient than even the LED headlights just now reaching production cars. The laser light is filtered to make it safe to look at, and puts out 170 lumens per watt, up from an LED headlight's 100 lumens per watt. Laser headlights also throw twice as far as LED headlights. BMW included laser lights as an option on its i8 model, although this feature is not yet available in the US because the Department of Transportation is yet to approve the technology.
BMW will put a new twist on laser headlights at CES, however, taking advantage of their flexibility. The concept car will use its various sensors and data sources to shape the laser light thrown in front of the car appropriately for the terrain. Although we will have to wait and see what precisely BMW has on offer, this type of feature could be used to adjust the angle of the headlight when going up or down a hill, shorten the throw in a well-lit city, and of course prevent the light from shining into other drivers' faces.
As for the tail lights, organic light emitting diodes (OLEDs) are a technology. Rather than a projector, this low-energy display technology makes a luminescent surface in any color you desire. BMW will show off OLED tail lights on its concept car, the advantages being that it makes for smooth illumination across the entire panel, can show different tail-light patterns for different circumstances, and requires less intrusion into the body of the car than a typical light and reflector.
I'll be posting full details when I see BMW's new concept car at CES 2015, so stay tuned.
