What do the Cornering Lights on the LCI/2008 Cars Do?

And how well do they do it? I understand that flash-to-pass is now handled by the Bi-Xenons and that the Cornering Lights replaced them.

Thanks.

Cornering lights work pretty well but only at slow speeds. They're tied to the steering wheel angle and they're tied to the turn signals so they turn themselves on and off at the proper times.

As far as lighting the corners, they work very well. Overall, the headlights are improved from the pre-LCI cars...

The cornering light is integrated in the headlight where the previous
high beam lamp was located. The light beam is reflected to the
side by the special shape of the deflector and the position of the
H3 bulb. The cornering light cannot be ordered as a separate
option as it is an added function of Adaptive Headlights (SA 524)
The special arrangement of the mirror surface in the reflector and
the special shape of the lens deflect the light beams to the side
while preventing forward dazzle.
The cornering lights illuminate when the respective turn signal is
operated and or the steering angle sensor indicates a turn below
40mph.
The angle of the steering wheel to activate the cornering light differs
depending on the type of steering system used (power steering
or active steering), steering gear and steering gear ratio. The
steering wheel lock to activate the cornering light when the vehicle
is stationary is between approximately 40 and 75 depending on
the type of steering.
Flash to pass does not affect the cornering light nor does the hazard
function activate it.
Note: Both cornering lights come on when the reverse gear
is selected to help illuminate the way.

Switch-on conditions for the cornering lights
The corresponding cornering lights will illuminate depending on
the following criteria:
The selection of the turn signal below 65kph/40mph
Steering angle input while driving below 65kph/40mph
With vehicle stationary and engine running a steering angle of
40 to 70, depending on the steering system
With reverse gear engaged both cornering light will illuminate


Switch-off conditions for the cornering lights
The cornering lights switches off in the following conditions:
Adaptive headlight off
Direction indicator off
Directional constantly on above 40kph/25mph
Steering angle is reduced ( by 5-10 after switch-on condition
with vehicle stationary)
Steering angle increased while driving above 70kph/43mph
While drifting (Steering lock and yaw rate in opposite directions)
While turning at a traffic light there is a 4 sec time out
Headlight temperature too high (headlight protection)
Reverse gear disengaged


Advantages of the Cornering Light
The cornering light makes it possible to recognize people or traffic situations earlier in the
turning area.Pedestrians are recognized before the vehicle actually turns.This function represents a considerable increase in safety for thedriver and other road users.

The special arrangement of the mirror surface in the reflector and the special shape of
the lens deflect the light beams to the side while preventing forward dazzle.

Thanks, couldn't have hoped for a more complete technical reply. I've seen your other posts, glad to have your contributions.

I just hope that nobody ticks me off and id be forced to defend myself and I have got such a New Yorker attitude and tend to lose it.Last time it was a BMW parts guy accusing us techs of throwing parts at every vehicles.If this was true,why do we have to ask PuMA for authorizations??? And before we even ask we would need thorough diagnostics and only as a last resort we have to contact PuMA.For now I shall continue to educate the masses because of your passion for these vehicles that I also possess.Lets face it,the more you know the less we have to explain what work was or has to be done and "together" we can correct a problem on a timely manner.But thats just me!

As you're aware, on pre-LCI E60s, there is not separate high beam on cars with bi-xenon headlights, and the second lamp location is used for flash to pass and DRLs.

How is flash to pass accomplished on LCI cars with bi-xenons?

LCI cars simply flash the bi-xenons instead of having a dedicated lamp...

Yes, apparently the warm up (full brightness) time is much faster (a few tenths of a second rather then a full second) compared to Xenons of a few years ago. So using them to flash is acceptable. Having seen this myself though.

Life Cycle Impulse, I believe. BMW speak for model mid-life refresh/facelift.

So what cars are the LCI cars?

On my 08, the cornering lamp is the inner angel eye on each side. it comes on at slow speeds when I turn a corner or pull into a driveway or parking space. I know because I see the reflection from the side of my office building when I pull in every morning.

On the E60, LCI started with the MY08 cars.

You have to get a really big spoiler before the LED lights can be added. Use a big hammer to put it on. Then get the Tornado, +100HP and +35MPG!

Just to add a bit more..

Not so much the lamp is flashed to a higher beam or anything like. A motorized shade is momentarily lifted up to allow the beam to project further/higher.

I think this is also why some people feel their beams are adjusted too low because there is a definite line where the light is and where it stops. "Normal" low beams just sort of fade from a bright spot to not so bright.

Edit: Just to clarify my own thought some more:
What I just described is the difference between high beam and low beam. Flash to pass using the xenons is a programming option because moving the shade is a bit slower than flashing the inner lamp.
