Mercedes-Benz is adding headlamps that swivel to its E-Class range in South Africa from May.

The active cornering headlamp system was jointly developed by

Mercedes-Benz and Hella and is based on the Bi-Xenon headlamps fitted to the Mercedes-Benz E-Class.

At the heart of the system is a microcomputer integrated into the electronic data network, which is continuously supplied with information from the steering-angle and speed sensors. Each Bi-Xenon module is equipped with its own electronics unit and an electric motor, which swivels the lamp horizontally.

The active cornering headlamp system operates on both low and main-beam. The headlamps react quickly to changes in the steering wheel angle when the vehicle is moving rapidly, and the swivel mechanism reduces speed when the vehicle is moving slower. This means the light is distributed as the driver requires.

Mercedes-Benz says the system improves illumination of the road ahead by as much as 90 per cent. Whereas conventional low-beam headlamps are able to provide illumination for a distance of some 30 m when entering a curve with a radius of 190 m, the new headlamp extends this range to about 55 m.

Bi-Xenon technology means that only one lamp is required for both low and main beam. On main beam, the whole light beam is utilised. When the driver switches to low beam, a shutter is inserted between the lamp and the lens system, blocking out part of the beam.

This system is offered as an option at R12 000 across the range and standard on the E55 AMG.
