Laser headlights are just the latest bit of high-tech to help drivers see further at night and make the roads safer. LEDs already offer several advantages in terms of light output and energy use, and lasers simply take that a step further.

When BMW’s petrol-electric i8 sportscar goes on sale next year in SA as the first production car to use laser lights as an option, its illuminated range will be 600 metres – double the range of LED lights.

Laser lights have far lower consumption than LEDs and they’re also a lot more compact; to get the same illumination from LEDs the diodes would have to be around ten times larger than they are now.
