Bi-Xenon headlight system
Bi-Xenon, a headlight system with projector module, is based on gas discharge technology. The system combines high and low beam into the same lamp.
Due to legal requirements (regarding low beam) for this type of lamp, the vehicle must be equipped with automatic headlight levelling.
There are two gas discharge lamp modules (GDL) - one for each headlight. The one located on the driver's side of the vehicle serves as "master" and communicates with the central electronic module (CEM) via LIN communication.
The other gas discharge lamp module (GDL) serves as "slave" and communicates with the "master" control module via LIN communication.
The gas discharge lamp module (GDL) and ballast are integrated into a single unit and are mounted behind the headlight in the wheel arch liner.
