BMW draws plans to use lasers for headlightsby Gavril Mankoo
Headlights have been an essential part of vehicles ever since human beings deiced to take their wheels out at night. Now, BMW is busy working on headlights of the future, using one of the most promising technologies around that could change the way we drive at night, lasers! Using laser headlights, BMW is developing a combination road lighting system and pedestrian deterrence weapon. The automotive firm hopes to create smaller, more efficient and brighter headlights, and laser technology seems to be the answer to it all. Laser diodes are a hundred times smaller than LEDs and are usually a thousand times brighter too. This could lead up to fuel savings too, given that lasers are twice as efficient as LEDs.
