In the sticks here most lanes need to be taking at a reduced speed and no street lights for miles, never had lasers before but at least I know whats happening now, doesn't make much sense to me though and why would your speed be a factor in it's operation

What I'm still not sure about, though, is whether the laser lights are disabled below 37mph regardless of whether main beam has been activated automatically via HBA or manually via the stalk (the 'old-fashioned way'). If there are genuine concerns about them being too bright around town you'd think they'd be disabled below 37mph regardless of how the main beam has been activated but to satisfy my curiosity I think I need to do a little experiment next time I'm out in the dark! |

I wish rear fog lights wouldn't turn on at all. C*nts that turn them on in city centres should be dragged from their cars and shot.

I’m pretty sure that it’s only the lasers that switch off below 37mph (for the reasons given above). The dancing lights continue to operate below this speed, as long as the vehicle has determined that high beams are appropriate.

Makes no sense to me either. I've owned BMWs for 40 years now and still struggle with German logic!

Checked tonight you activate the HB and kick into gear at 37 MPH you then can reduce your speed to 20 MPH and they still function, dancing lights still working, turn off at 19 MPH and did not see the dancing lights work at all, turn off in heavy fog and turn off when the road is well lighted, not convinced they actually work in lighted conditions including the dancing lights, manual HB at slow speed and auto HB at speed are the same to my eyes, that all said I am more unsure why speed has any reason behind it if they turn of when streets are lighted, but that’s how my lights work

That's how I thought but couldn't see it, give it another try tomorrow, drive down this lane daily, fog did come in soon after and could of affected what I was seeing

Haven't checked mine yet but how you describe it is how I'm assuming they'll work (i.e. no laser lights below 37mph regardless of whether main beam is activated manually via the stalk or automatically via HBA). IMO it would be illogical for them to work any other way...

The operative word with HBA I guess is "assistant" not "replacement". For the most part it will assist you but it cannot, logically, be perfect. When it isn't, you can undertake the arduous task of moving the lever yourself.

Agree moving the stalk is what I have done for many years and a non issue now I understand what's causing it to suddenly turn off, that said still unsure why speed is a factor especially if lasers do not function at a set speed anyway

I can think of very few places where I'd drive at <19mph and yet want main beams on. In fact, I can't think of any. But I do realise there will be exceptions.

You would want to down our lane but I understand your point. I was just confused why it was doing it. Non issue now I understand, even though I am not sure why

I take your point but I've always thought - obviously incorrectly - that HBA would assist by activating main beam whenever lighting conditions dictate and another road user wouldn't be inconvenienced. So I wouldn't expect main beam to come on in urban areas where the roads are lit and I wouldn't expect main beam to come on and/or stay on when there's another car around and the driver could be dazzled. However, if it's pitch black and there are no other cars around I'd expect HBA to activate the main beam regardless of speed - but it obviously doesn't work that way so, like you say, back to moving the stalk it is!

I assumed the logic was just that you don't need to see so far when you're going slower. |

And what I think is now also being suggested is that, if you're using HBA, the main beam will drop to dip beam as soon as the road speed goes below 20mph (so even if you've got selective beam you lose that functionality at low speeds). That means if you're on (say) a tight, twisty, road you need to select main beam via the stalk to make sure it doesn't go to dip around any slow corners. I will see what my car does the next time I have it out in the dark but haven't felt inclined to take it out specifically to check! |
