Cornering-light mechanics of Pre-LCI vs. LCI Adaptive headlights

For instance, when turn signal will not activate the cornering feature of the light, it may also disable the headlights turning along with the steering wheel, but I do not know for sure about the later. It is not clear if the turning of the LED through a turn is part of the adaptive function, but I suspect it is. Only when the switch is in the full left, or adaptive position will the adaptive features work.

I love the arrogance you display, it's truly impressive. Apparently you've been riding with me and saw me switch it off of auto? If you read what I typed originally you see that I said "The '18 lights actually move with the steering wheel..." which according to your theory shouldn't happen if the lights aren't in auto correct?

You sure? CanAutM3 seems to point out some distinct differences.

So rude of me to check again...

Thanks, I will. I intend to keep it a long time.

On the pre-LCI there was a reflector fed by a small LED array inside the vertical element inside the cluster near the grill (see picture below). Now this arrangement has been replaced by the "horizontal tying" illuminated bar of new look hallows. I am not sure where the cornering light resides on the LCI clusters or if there is one altogether. My best guess would be that it resides where the flasher used to be. Someone with an LCI would need to let us know.

No real lights where the old indicators used to be, just the one orange light. Of course the indicators are now above the headlights.

So if you activate the turn signal with the light switch in "Auto", is there a white LED array that illuminates for the cornering lights?

No. I see no change in the headlights when activating the turn signals.

Curious. What occurs when you turn the wheel toward that side?

I can see the headlights move a little to the left and right with the wheel.

Well, its been a little while and still no solution, perhaps this is a BOT post, but I am curious to see it play out to the end.

I would be hard pressed to believe that the new LCI Adaptive Headlights have no cornering light capability. I am fairly certain BMW would not change the design in this direction. The potential might be there if they had developed some fog light assemblies, but cooling flow paths on our F8x won't permit it. My arrogant-self actually says NFW did BMW remove the capability.

Based on the assumption you have the light switch in adaptive mode, and neither turn signal, nor turning the steering wheel at low speed, initiates lighting up the corner, my arrogant-self believes there is something wrong.

With your insinuating (no Observable Quality Evidence) the switch is set correctly and the cornering lighting still do not light up the corner, than there is either a problem with the operator, light pods (failure on both sides is an amazing coincidence), or the adaptive switch is defective and may have been wired incorrectly in your car. If the later two items, which I believe could potentially be true, take it to the dealer ASAP. Is it possible you do not have adaptive lights on your car???

According to jwar93, whom has access to things BMW, the actual cornering LED is still in the Adaptive LED ICON housing, according to his technical contact. Also, the cornering LED assembly is located in the similar position of the previous generation of adaptive headlight, but apparently hidden a little bit more.. I still would like to see an explosion view of the ICON lights showing the assembly in greater detail. I haven't found one yet, I can only see the older version online.

Let us all know how this gets resolved, or.....my arrogant-self thinks you might need to post here :

I just looked at your picture again. What is the slot circled in red? it looks like it might be LEDs that could shoot out the side. If it is, this means the corning light assembly was moved to the outboard side of the light pod.

Yep, still no answers from me. Drove the M this morning before the sun came up and still no changes from my initial report in how the lights respond to the steering inputs or the turn signals (of course while in Auto/Adaptive mode).

DBACE, I completely agree with you in that I'd be hella shocked if they removed this capability which is why I posted this in the first place. I double checked before I posted, then triple checked and for the 4th time checked again but I can't for the life of me figure out what's going on. I got a message in with my BMW genius, still awaiting his reply.

ICON lights and no adaptive? Build sheet says, adaptive... like you said maybe something is wired incorrectly (or built on Monday/Friday). Or they coded out the corner feature? The car has the Executive package...

Yeah I saw your asinine post, where you assume everyone who posts a question hasn't

I'm a big boy, if I'm the cause of this error I'll gladly eat my hat but until then you could be a bit more open to the thought that maybe BMW drops the ball every now and then. Or maybe they actually did the unthinkable and removed a great feature without anyone noticing and I'm just the person who happen to spot it because I'm a bit OCD.

As for your 2nd post, the part you highlighted is just the housing that holds the orange parking light. No LEDs in that circle you drew, sorry (I got excited and even went to check the car).

you can zoom and see the shiny plastic.

Will try and test this out today with one of the '18 F80's I have in-stock and will see what I find.

[jwar93]

Luckily my BMW guy came by today, from what we could deduce looking at some schematics he has and talking through things, we think that the interior headlight rotates/changes angle to act as a cornering light like on some previous BMWs...will keep digging into this and see if I can find anything different/definitive.

jwar93 If you can, please post pictures and video would be superb. We are all sitting on the edges of our chairs....well I am anyway. Thanks for looking into this.

I forgot to mention that when the transmission is put into reverse both cornering lights activate. OP, have you brought your car to the shop and if so what did they say?

[Aaaaaaaaa]

This thread is like a public private message convo lol

Hadn't tried that yet, or noticed that feature.

The car is going in later this week for a scratch repair that was found at delivery pickup. I'll talk to the shop when I'm there to see if we can compare some 16's they have on the used showroom floor.

I don't think the 2018 models have cornering lights. If you check the FLE settings using E-Sys, the only light groups that are available/defined are Low Beam 1 and 2, High Beam 1 and 2, Sidemarker, Daytime Driving Light and Indicator Light (see Lmm01_Name through Lmm12_Name). Your high and low beams will swivel up to around 40mph (can be modified via coding). In addition, if you enable Variable Light Distribution and Glare Free High Beams your headlight beams will adapt according to speed (aimed lower at low speeds and higher at high speeds) and the camera (if you have KAFAS2) is used to control your high beam light pattern. For example, the inner high beams automatically switch off and the outer high beams swivel to the outside to create a light tunnel when following another vehicle. Similarly, the system will first swivel and then turn off the driver side high beams when it detects oncoming traffic. Pretty cool!

Seems odd BMW removed the cornering lights.

I find it to be a cool function, and helpful under certain circumstances (maybe that's why it was removed - only sometimes helpful).

I also looked at the 2018 M4 manual with adaptive lights and when I searched for cornering lights, nothing came up. This is based on manuals from my 2016 M4 with adaptive LED’s and a vin number from a 2018 M4 with LCI adaptive LED’s.

[Arcades]

The cornering lights on the pre LCI cars weren?t extremely impressive btw so I?m not surprised if BMW did remove it.

I have full LED on my 15? M4 and I don?t see the big deal. It turns only a few degrees each way.

I?d rather have the LED aim higher considering how annoyingly low it aims at low speeds. So much so it?s dangerous in urban areas. In fact BMW got such a low score on their LEDs they responded to the research.

It?s around here on BP some where like a year ago.

[Vectors2final]

Negative... cornering lights aren't "turning". They're illuminating the dark spot where you're turning to at night making left and right turns.

Example... You're making a left turn into your driveway and the area you are turning to is dark. With a cornering light, it will illuminate that dark portion before you turn in giving you better visability. In certain cases, they come on early with braking, blinkers and steering input.

The pictures below are a good depiction of the increased lateral lighting range provided by the cornering lights (pre-LCI). It is not negligible IMO.

Are we talking about the same thing... These are cornering lights.
