The BMW M4 Iconic Lights concept currently lives at the Las Vegas Convention Center, home to much of this year's CES, in a large tent in the middle of what is normally a car park.
This odd setting allows the M4 Iconic Lights concept to demonstrate its prototype illumination technologies to a small audience via an elaborate light and sound display.
The M4 Iconic Lights' laser headlight technology is similar to one that's available as an optional extra for i8s sold in Europe, which can illuminate the road for up to 600 metres ahead of the car and has anti-glare technology that dynamically blocks out part of the car's laser high-beam to avoid dazzling both oncoming and upcoming traffic.
In addition, the Iconic Lights concept features a laser-driven Dynamic Light Spot, which can illuminate pedestrians or animals lurking in the darkness within a range of 100 metres.
Also present on the concept car is a predictive dynamic headlight setup, which uses the car's GPS position and map data to aim the headlight beam into corners before the driver has turned the steering wheel.
There's also a car width marking system that can detect tight driving circumstances, such as trying to overtake on a narrow road, and project lines marking out the car's width on the road ahead, informing the driver of whether there's enough space to complete the manoeuvre.
At the rear the tail-lights feature a collection of artfully shaped light tubes powered by organic light emitting diodes (OLEDs). The indicators and brake lights on the Iconic Lights concept can be lit up as a block or in sequence, depending on the situation.
