BMW Builds a Headlight with Frickin' Lasers

Imagine the small fender bender in the parking lot. You're probably going to be looking at a good 3,000 dollar headlight/bumper replacement.

One step closer to my Electro Pedestrian Bastard Ray... Pity I'd have to drive a BMW to get it...

Not that this has anything to do with my computer  Paul ,how about blinding oncoming traffic in the glare

Because lasers travel in essentially one direction and they must be diffused to have a light spread, they would probaly be better for dealing with glare as the light is far more directional and thus won't have any leakage outside where you want it to be. That's what I really see as the primary advantage.

So it's brighter and more energy efficient...  How about life?  I'd imagine these cost a pretty penny to replace (as do the LEDs).

LEDs last a lot longer than a standard bulb (is why I've replaced all the interior and exterior bulbs in my car with LEDs (headlights and foglights are HIDs), the laser should last insanely longer.

 

But ya, if you DO have to replace the part out of warranty, the cost will be high. But hey, if you can afford a BMW, you can afford to replace the headlight.

Hey, I did the same thing. I replaced all my lamps with LEDs and my headlights with HID drop-ins. And yes, I have read all about how HID replacement lamps are "bad" mainly due to cutoffs err, being off. I did a side by side with the original Halogen bulb and the HIDs and the top cutoff was actually BETTER with the HID (more light sprayed to the outside tho).It also helped with the backup lights being too dim in the Ody.

The interior with 6500K LEDs looks great with its pure white light.

All in all a worthwhile project for the two cars.

The standard reflector housing in most car headlamps are not designed for HIDs and they perform very poorly, with the light being scattered. Projector housings are designed to work with most HIDs and perform a lot better.

Also, 6500K is more of an Ice white (hint of blue) than pure white. 4300K-5000K is more of the pure white, 4100K has a hint of yellow in it.

I have 6000K switchbacks in place of my OEM turn signal bulbs (white when parking lights on, and amber/off when turn signal engaged), and compared to my Silverstar Ultras (4300K Halogens), the switchbacks have a blue tint to them, and my Halogens are more pure white.

"And if you're worried about burning a hole in a pedestrian caught in the glare, don't be. Laser light in headlamps is first converted into a form that isn't harmful to living creatures, so you won't leave a trail of burned up carcasses as you motor through the neighborhood."

 

So little Joe The Haxxor will remove the headlight catalytic converted and voila... Darth Vader on wheels...

It's doubtful that, even unscreened, the lasers they are using would radiate more energy than it would take to be mildly irritating, possibly give you a sun burn after extended exposure.

What is far more likely to kill whatever you happen to be shining your headlights on is the large 1-2 ton chunk of plastic and metal hurling at them at 60 mph.

You lost me there

That ... would actually be a pretty hot-looking headlight....
