As opposed to a "dynamic (swivelling) cornering light".

Dans les virages serrés, les virages en S, les croisements et les manoeuvres de stationnement, le conducteur manque d'informations sur ce qui se passe directement sur les côtés de son véhicule ou dans l'angle avant de son véhicule. C'est en pareils cas qu'intervient l'éclairage statique de virage, qui vient judicieusement compléter le feu de croisement et éclairer les zones que nous venons de mentionner. La nouvelle Audi A8 est le premier véhicule au monde à être équipé d'un tel éclairage statique de virage ou d'un éclairage d'intersection. La première homologation de ce système au plan mondial a été rendue possible par l'agencement astucieux du réflecteur de l'éclairage d'intersection directement sur les feux de croisement. L'ÉCLAIRAGE STATIQUE DE VIRAGE EST AUTOMATIQUEMENT CONNECTÉ AUX FEUX DE CROISEMENT LORSQUE LE CONDUCTEUR ACTIONNE LE CLIGNOTANT pour tourner à une intersection ou bien lorsqu'il circule sur une route présentant des virages serrés. De plus, cet éclairage est fonction de la vitesse. A cet effet, un appareil de commande évalue les paramètres suivants : vitesse, angle de direction et signal de clignotement. Afin d'en augmenter le confort, la mise en marche ou l'arrêt de cette fonction d'éclairage n'est pas brutale; elle se fait progressivement en fonction de paramètres temporels spéciaux, qui prennent notamment en considération la vitesse du véhicule. Un tel système évite tout arrêt intempestif de la fonction sus-décrite à des vitesses plus élevées.

Read from "Combining the high-tech MMI system ..." here:
http://www.leftlanenews.com/audi-a8.html

The Audi A8 looks out on the world through newly designed headlights – with xenon plus units and the innovative full LED headlights, a technology Audi was the first to introduce worldwide in the R8 high-performance sports car. The adaptive light system augments the xenon plus units – it controls THE SWIVELING MODULES [this is different] so that they always provide the perfect lighting for intersections, the city, country roads and highways. The new all-weather light integrated into the headlights replaces the fog lights. Their traditional location in the air intakes is now occupied by the radar sensors of the optional adaptive cruise controlwith stop & go function.
A technological breakthrough from Audi is the networking of the headlight control unit with the optional MMI navigation plus. The navigation system analyzes the route ahead and relays the data to the light computer to activate highway lighting with its extended range while still on the ramp to the highway, for example. BEFORE ENTERING AN INTERSECTION, THE SYSTEM ACTIVATES THE CORNERING LIGHT, which provides wider-angle illumination and thus enhances safety

It's called a STATIC TURNING LIGHT here, in the section on "Lights" on page 80:
http://www.audi.se/etc/medialib/ngw/se/pdf___filer.Par.0007....

The light is switched on when the indicator is activated. It is thus different from the "dynamic cornering light" which swivels as the steering wheel is turned.

Other manufacturers may have other terms for this, but Audi/VW call them "static turning lights":

The STATIC TURNING LIGHT INTEGRATED IN THE FOG LIGHTS provides additional safety and convenience at junctions as well as when parking. ...

There's also a reversing camera, a tyre pressure monitoring system and even what VW refers to as a STATIC TURNING LIGHT. ...

I guess the system turns off above a certain speed since it's considered you don't need this lighting for overtaking or motorway lane-changing.

BTW, the procedure used in finding the above was as follows (as indicated by the refs quoted):
1) find a website with the problem term, ideally with the name of a car manufacturer using the system;
2) search for that manufacturers name with keywords lights, car, intersection;
3) within the relevant-looking hits that come up, look for pertinent information (use CTRL+F to find words; anyone who uses the Web and CTRL+F (loads of people don't know about it) can pretty much dispense with ProZ!)
4) Having found a likely translation, confirm by websearching that expression.

Step 1) also helps you find out more about the problem term, in this case precisely what the éclairage statique d'intersection is, how it works, etc., so that you will know when you come across the corresponding situation in English, or to help you target relevant search words in English.
