The European laser headlights project up to 600 meters...the limit a headlight can project is much lower here so the EU and US headlights are physically different. Even if this law passing the anti-dazzle is passed we will not see the full benefit of the laser lights.
For US customers, the laser lights are basically a cosmetic upgrade. |

Because the FDA made BMW change the headlight design to include a safety switch if the housing was broken, it disables the laser from functioning, and I'm guessing BMW didn't care to include that for the original design. Hopefully, that is the only thing that's different, and the rest of the functionality still exists.
I've heard that some coders have been able to make the US headlights work, at least with most of the capabilities. I'm going to wait to see if BMW enables whatever functionality, and if not, I'll check into a coder and see what they can do. BIMMERCODE author said he wasn't planning to try, at least yet. |

We have tentatively determined that the proposal to permit ADB and subject it to requirements and test procedures would lead to greater benefits than maintaining the status quo in which ADB is not deployed. The anticipated benefits are a decrease in fatalities and injuries associated with crashes involving pedestrians, cyclists, animals, and roadside objects due to the improved visibility provided by ADB. The improved visibility is a result of increased upper beam use and an enhanced lower beam. Although it is difficult to estimate these benefits, NHTSA performed a data analysis to explore how driving in better light conditions affects pedestrian and cyclist fatalities. The analysis focused on pedestrian/cyclist fatalities and injuries under various light conditions and explored the correlation between pedestrian/cyclist fatalities and injuries with light conditions, as well as several other risk factors (location, speed limit, alcohol use, and driver distraction). The analysis used data from the Agency's Fatality Analysis Reporting System and the National Automotive Sampling System General Estimate System. These databases contain detailed information on crashes involving fatalities and injuries, respectively, including information on the conditions under which the crashes occurred. This analysis suggests that the size of the target population—pedestrian and cyclist fatalities that occur in darkness—is 15,065 over 11 years or 1,370 per year. This analysis is discussed in more detail in Appendix A. The Agency tentatively concludes this analysis demonstrates that a properly-functioning ADB system could provide significant safety benefits beyond that provided by existing headlighting systems.[133] |

Here are the test results from the IIHS. https://www.iihs.org/ratings/vehicle...019#headlights Edit: Since not all will read the test regimen, it should be noted that in the tests performed by the IIHS the lasers did not come into play since the speed at which they run the tests was slower than the threshold for the lasers to kick on.

Simple solution is to raise the headlight slightly. They appear to be limited by coding but also configuration.

You all have seen lasers right?
Since when did they start behaving like a hand held torch light with a gorgeous spread - that you expect it on your vehicle. As the name suggests, when the lasers turn on you will see road reflector thingy on the lanes, side of the roads and all the road signs brighten up way more and way way far beyond your LED hi beam light reaches. That is laser for you. If you are doing say 60-70mph and do hi beam when possible you will see more distance but with lasers the reflectors pop out more than a 1/4 mile beyond. Consider how much this will help your confidence on interstates doing 60mph turns. Whether it's worth for you you have to decide. But I don't think anyone can argue about the cosmetic addition the turn lights, angels and 4 headlights add. |

Laser Lights
Quote:
I have just got laser lights on my G05 50d , I have to say they are fabulous, my commute is a mix of back country lanes and motorway and they just make such a difference, they literally hunt down the edges of motorway and country lanes, I am very impressed. My F15 had auto lights and they seemed to just annoy everyone, these are definitely worth it. In the uk the nights are drawing in, the other night I was blasting down my country lane, the lights illuminated the edges brilliantly, and picked out a family walking along the country lane well in advance, I was so impressed. It was so good to have that clear early view of the road. Sorry to hear others aren't so impressed, but I have to say I am, and I haven't annoyed anyone yet either |

FWIW, the laser diodes face backwards and are not in the visible range. They excite a phosphor in the back that converts that energy to the visible range, and that light is directed by a reflector. IOW, they do NOT face forward, or are in the visible range, so their spread could be anything that the engineers wanted.
In the USA, the FDA (not DOT) forced BMW to add a safety switch to shut the lasers off if the housing was broken before they would approve their use in the USA (the DOT controls lights, but the FDA controls lasers, so it took awhile to get both of them happy to approve their use in the USA). They were worried that without that, the invisible light from the lasers could possibly end up pointing forward and blind someone. Whether that is anywhere near a likely situation, can't say, but that's why they forced that redesign. No idea how well it works. |

I have an x5 with led and an x5 with laser(uk) the lasers are blindingly bright and visibility is much better.

I have driven my X5 for two days now and I tried to see the difference when the lasers come on, but if there is a difference, it is _very_ small. I tested this on a straight road with some traffic signs on both sides, but .. nothing. Well, I can _imagine_ one more small LED being switched on, but nothing I would call "blindingly bright" or that visibility was any better. Has anyone installed a LED bar to G05 and wired it to switch on whenever these lasers switch on? |

Putting aside all of the spotlighting, anti-dazzle, etc. that is available in some regions the lasers are mainly focused to the lane you are driving in. The best way to see them, other than having something far in the distance in your lane, is to test them going uphill. You will see them kick on and the beams projected on the road.

I thought European head light regulation is more advanced than North America and therefore the laser lights are fully functional there. On this side of the pond laser lights are code-restricted due to the archaic laws that is expected to be amended soon, awaiting final ruling; ironically the adaptive driving beam (ADB) change is requested by Toyota, not BMW.
