Laser LED's are not used as far as I'm aware for vehicle lighting as they can seriously damage eyes.
LED driving lights are available and are, or can be, very powerful, a 10 watt LED can produce a similar light output to an 80 watt tungsten bulb.

Laser are starting to be looked at for vehicle headlights with some new lighting systems.
keep your eyes peeled.

Didnt think they'd actually launched theirs yet? its been BMW and Audi fighting over who got there first for just over a year.

Not worth the money IMO I get almost identical performance from mine which where £45 a pair of 54w CREE LEDs off ebay (Sunyee International) with a 2 year no quibble warranty.
Only nice feature was on most you can switch between DRL style lights and main beam.

You sure they are not just using the term Laser for marketing? There is NO light spread with the collimated light from a laser which would make a pretty useless headlight.Too late, BMW are fitting Osram Laser headlights in their 8 series vehicles already
I think they are using CREE type LED's under a brand name to impress the gullible.

No they are using a blue laser with a phospher unit to make the blue to White (same as white LEDs)
Quite clever stuff, but addresses the drawback of LED, LED by nature is an allround light source, which then needs lenses to focus it, Lasers are the opposite, they are highly directional, so they use a small cluster of lasers and no lenses so reducing losses in the optics to almost zero.

So feck the potential for eye damage in oncoming drivers when the lights are badly aimed. Tungsten is an all round light source and produces a perfectly acceptable beam pattern, CREE LED's can and do produce more light and a better beam pattern than Tungsten, they are so far just not a straight swap in old headlights. Plenty of manufactures are using them.

Theres Lazer/Laser the brand of lighting stuffs for vehicles, seem to be mainly LED these days.
Then theres Laser Headlights, as fitted by audi/bmw.
The scope for eye damage is limited to the brightness, rather than the fact its based on laser technlogy, the phosperous converts the wavelength to visible light, which is non damaging, the lasers are arranged so if there is any damage to the light converter, the laser is not emmited to the front, looking at the info, the lasers point downwards, the light is then converted to visible light, and sent through a prism to point forwards.
