BMW engineers are currently working on the introduction of laser light technology as the next logical step in car light development. Laser lights offer a vast improvement over the stock LED bulbs, currently used in luxury cars because lasers use less energy, are brighter, smaller, and can be directed at a smaller area.
LED lighting generates only around 100 lumens per watt, but laser lighting generates approximately 170 lumens, meaning they’re much brighter. The new technology is much more efficient and interestingly, because lasers are much smaller, designers can create very thin lights, seen on futuristic concepts. BMW also sees no reason why they can’t implement all the familiar lighting functions to lasers such as Adaptive Headlights, the Dynamic Light Spot spotlighting system and the Anti-Dazzle High-Beam Assist.
