With the beginning of series production of the BMW 3 Series Coupé (E92), new functions for exterior lighting are introduced. The bi-xenon headlights are standard equipment.
Note: Option 524 only in conjunction with optional extra 522.
Option 524 ”Adaptive Head Light” is only delivered together with optional extra 522 ”Xenon light for low beam and high beam function”.
In the US version, optional extra 524 is series standard.
For the E92, the following functions for the exterior lighting are new:
Note: cornering light only in conjunction with optional extra 524.
The cornering light is a subfunction of optional extra 524 ”Adaptive
Head Light”.
The following components are described for the exterior lighting:
The bi-xenon headlights are standard equipment.
The bi-xenon headlight with its smaller design is well suited to the Coupé-style body design with the flat engine bonnet.

With an ellipsoid reflector and a 70-mm lens, the light is generated using xenon technology of the latest generation. The swivel module can be adjusted horizontally (Head Light) and vertically (headlight vertical aim control) using an electromechanical unit.
The following control unit activates the new functions of the exterior lighting:
All the functions of the exterior lighting are controlled
by the footwell module (FRM). The footwell module is connected to the vehicle with
3 plug connections. Two 51-pin
connector connect the main wiring harness. Another 26-pin
connector is for the connection to the dashboard.

The following system functions are described for the exterior lighting:
The cornering light is linked to the Adaptive Head Light
(option 524). The cornering light increases passive
and active safety at night. When making a turn or on tight bends (serpentines), the area beside the roadway is given additional illumination. This is also provided on parking. The special styling of the headlight lens prevents dazzle towards the front.
Depending on the country, the cornering light is switched on during cornering.
Requirements for switching on the cornering light are:
The footwell module uses the following signals to activate the cornering light:

At driving speeds greater than 70 kph, the cornering light is no longer switched on.
When backing up, the footwell module switches the cornering light on up to a speed of 35 kph:
With the turn indicator switched on:
when the vehicle is stationary, the cornering light is switched off automatically after approx. 4 seconds, e.g. waiting at traffic lights. However, the cornering light can be switched on again using the turn indicator / main-beam switch (up to 3 times) until a certain temperature is reached at the reflector. A temperature model protects the headlights against excessive thermal load. After a
cool-down phase, the cornering light can be switched on again.
The switch-off conditions for the cornering light are country-dependent.
A fixed additional reflector with an H3 bulb is built into the main headlight with cornering light.

Note! Temperature monitoring
by temperature model!
A temperature model in the footwell module (FRM) calculates the temperature at the reflector. The temperature at the reflector must not exceed a certain value. If a critical temperature is reached, the cornering light is switched off. After a cool-down phase, the cornering light can be switched on again.
In the same way as the sidelights, the daytime driving light is generated exclusively via both light rings. Daytime driving lights increase safety as the vehicle can be seen better.
The light rings are activated with pulse-width modulation. When the low-beam headlight is switched on, the brightness of the daytime driving lights is reduced to that of the sidelights.

A central light source supplies both light rings via a reflector split two ways. The inner light ring is illuminated via a reflector. Via another reflector, the light is guided through 2 optic-fibre cables into the other lighting ring.
The footwell module (FRM) activates the central light source using pulse width modulation. This means that a higher light intensity is generated for the daytime driving light than for the sidelights. The possibility for dimming means the lighting functions can be implemented with a single bulb.
The daytime driving lights can be disabled in the Central Information Display
(CID) in the ”light settings” menu. On vehicles without CID, the daytime driving lights can be disabled via the instrument cluster. Exceptions are countries
with legally prescribed daytime driving lights.
The welcome light extends to the exterior lighting. Parallel to the interior lighting, the following are activated on unlocking the vehicle:
The welcome light is only switched on if the light switch is in the automatic or dipped beam position. In positions 0 and 1, the welcome light is not switched on. This means the customer has the possibility to deactivate the welcome light.
As childproofing, the welcome light can be activated a maximum of 5 times (20 seconds).
The footwell module (FRM) switches the welcome light off after approx. 20 seconds (dimming).
The ON period of the welcome light can be extended to a maximum of 60 seconds.
To do so, while the welcome light is active press the ”Unlock” button.
For option 522 ”Xenon light
for low beam and high beam function”, optional extra 896 ”Daytime driving lights” is eliminated.
Adaptive Head Light is standard equipment.
