"Laser headlights" feels like false advertising, isn't it a phosphor that's "pumped" by laser light? Still interesting either way.

AFAIK that is exactly the case. WL also offers kind of optics for their arctic using this way to make it a flashlight.

Why are they not legal in the US. Like Diachi and others have pointed out, they are not actually outputting laser light, they are using it to generate tighter beams from phosphor. Sorry about the size, I haven't got time to rescale.

Anyway, if anything they are safer than conventional headlights as you can see more of the road. :thinking:

As an avid car person, the i8's and Audi's laser headlights are not legal in the USA because the feds are worried in the event of a collision, the optics may become misaligned and permit high intensity laser radiation to escape the headlight enclosure. Lame

But yes, the technology has been tossed around in various car articles for a few years now. It's kinda cool, but still way inferior to HID's in actually seeing the road imo

Ahh, that makes sense. Once the technology has matured some I imagine they'd change the regulations?

Considering the other aspects of a collision... the raw kinetic energy of a vehicle, the acid in the battery, the scorching shrapnel of a smashed engine block, the shards of glass everywhere, the explosive charges in the airbags, and countless other things... Why is it a bright light would be proportionally relevant in the slightest?

I wonder what those headlights look like to oncoming traffic. If it throws that much further, it is probably blinding in high beam setting.

Probably better than HID lamps in stock housings or lifted trucks without adjusted headlights... :whistle:
