I'm guessing like on other new redesigned BMWs that only the top trim Icon Adaptive ones will net an IIHS Top Safety Pick+ rating? FWIW, I had a G01 X3 loaner with regular LED Adaptive lights and there was a discernible difference at night compared to the LED Icon Adaptive lights on our X3.

5 years?

I thought these cars had explosives for built-in self destruct when I turn in the lease.

lifespan
reliability
cost

if its just " cause you can say you have laser", and no actual benefits, than meh.

again, people are looking for what is actually being sold, not what could be sold if bmw made that
In the EU versions up to now, the Laser portion only illuminates over roughly 70 KPH/45MPH.

LED is used under that.

Looking forward to this technology; I just hope the cost trickle down and it's not a $8,000 option, as it currently is on the US spec i8.

The US and Canada just approved "Selective Beam" for road testing on 10/2018. So we should have the same exact hardware/technology as the rest of the world by the time this hits the market - as oppose to currently..

I thought the "selective beam" feature was available with the adaptive led lights but just coded off in the US.
Also something I read on another post but didn't think about was these new lights in the snow. The old lights produced a lot of heat which tended to keep the lens clear in a snow storm but LEDs don't. No light washers in US so has BMW addresses this. Maybe with headed lens like mirrors.

Already coded in US version with the 2nd amendment.

It won't be $8000 stand-alone option--it's part of the $2100 Executive package (which requires the $2800 Premium package), if that makes you feel better.

This is the case with all US-spec cars, including the i8. High beams will be LEDs only under 44mph, and Laserlights and LEDs above 44mph. Also, headlights and high beams have to be set to auto, there is no manual control for the Laserlights.

On the i8, it's a $6,300 option, not $8k...not that that makes it affordable.

As was mentioned, on the G20, the Laserlights are part of the $2,100 Executive Package. On the G05 X5, it's a stand-alone option for $1,000 or part of the $2,050 Executive Package. On the G07 X7, the Laserlights are only available on the 50i (not available on the 40i) in the $2,100 Executive Package. On the G15 8 Series it's standard.

If you have a 2016 or earlier 3 series with the Adaptive LEDs you can code the european highbeam stuff to work (and avoid glaring other drivers). 2017+, no dice. Yeah, the swiveling and such will work right, but you'll blind anyone in front of you or oncoming.

Also, until the headlights are actually tested, we don't know if the laser lights really offer any benefit (other than looking cool). I'll assume that they will offer better overall visibility, but we need to wait and see.

Here's the link to the IIHS headlight testing on the 2018 3-series sedan. The LEDs are noticeably superior to the lousy base (which I think are LEDS on 2017/2018 models too):

https://www.iihs.org/iihs/ratings/ve...s-4-door-sedan
Click the "Headlights" section on the left of the screen to see.

However, LEDS aren't always noticeably superior to even the older Xenon (or HID) lights we had. Check the testing results for the X5.

https://www.iihs.org/iihs/ratings/ve.../x5-4-door-suv

Again, click the "Headlights" link.

This is why I didn't spec the LEDs on my 2016 X5. The LED low beams are slightly better than the Xenon on the driver's side but noticeably poorer on the passenger side. Plus the Xenon high beams are noticeably better in all directions. Given that I live in primo deer country, high beam power/distance is very important to me.

I know everyone digs the look of the new lights but I'd make sure they actual perform better before spending more money on them.
Good pointing all this out!

If my experience with the i8 Laserlights is of any indication, they absolutely do make a difference, even in US-spec. I got myself on an unlit road with lights on automatic and cruised at ~30mph with the high beams on. As I accelerated over 44mph, there was a notable difference in visible light output straight ahead. The Laserlights seemed to further fill in what the LED high beams illuminated. Now, the headlight enclosures on the G05, G07, G15, and G20 with Laserlights are pretty differently designed, but I wouldn't hesitate for a second to upgrade to them.

As a supplement to the LED low/high beams, the laserlight's primary purpose is to extend visible range, so that far objects are illuminated sooner. The light output or brightness at short and intermediate distances is not affected. In fact, overly bright lights directed at short distance objects probably cause more glare/reflection and adversely affect visibility by forcing the pupils to constrict. Unless one drives on UNLIT AND LIGHTLY TRAVELED roads at highway speeds, the laserlights won't come on very often at all, especially for urban drivers.

Hopefully the law is changed, if it hasn't been already.

https://www.reuters.com/article/us-u...-idUSKCN1ML2UW


Adaptive = Adjusts up/down/left/right

Selective Beam = I use the term VLD (Variable Light Distribution), is what does the magic with high/low beams and diverting light / creating light tunnels for vehicles you're following or vehicles that are approaching you. The gov. also refers to them as matrix lighting [specific to certain headlights/manufacturers it seems] or Adaptive Driving Beams (ADB).

RE: Hardware, it depends on the equipment the vehicle has. In the G30 for example, the base is Adaptive LED and the upgrade is Iconic [Adaptive] LED with high beam assist. Since it's the same hardware + camera used where the feature is permitted, it is simply disabled via coding for the US. It can be manually enabled.

Hopefully what the revised law means is a) going forward, we get to enjoy these features, and b) hopefully a simple update from BMW will enable it for models where it was turned off via software.

That announcement or news is a bit "deceptive," especially for those of us pining for adaptive/matrix-type headlights. It merely stated that DOT was "moving to approve" the new headlights, meaning DOT was receptive to "approving" them. The next phase would be 12-18 months of soliciting public feedback/opinion on such lights (not sure how that's possible when no such lights exist in the U.S.), after which the agency makes the final decision.

Regarding the two LED options, I wouldn't count on coding to turn non adaptive lights into adaptive lights. They've done this in the past, and they were two distinctive parts, one of which did not have all the components necessary for the adaptive functions. So if it's the same here, and by the looks of the different lights it probably is, coding isn't going to do much if anything. Non adaptive housings are much cheaper to produce, and they've not going to waste money putting parts in them that won't ever be used.
They are definitely available in the US market. There were recent developments in DOT regulations allowing further implementation of laser headlights. The G05 X5 and G15 8 Series also have them in the US market, but the lasers are just powered down a little compared to the European market.

On coding, what people are talking about is enabling the selective beam operation, also known as light tunnel. We can have automatic high beams in the US, but the function where the headlights angle themselves side to side to allow the high beams to remain on but pointing around oncoming cars is turned off. For this to be coded in, the headlights have to be adaptive and have auto high beam functionality from the factory.
My 2016 340i. LED adaptive. Anti dazzle was coded. Amazing.
