Static Bending Lamps

Static Bending Lamps

NOTE: The static bending lamps are not fitted to NAS vehicles

The static bending lamps, which are a standard feature on AFS headlamps, are designed to illuminate the direction of travel when cornering at low speeds. The static bending lamp functionality, which controlled by the LCM, is unique to vehicles with AFS headlamps and operates using inputs from the steering angle sensor.

The static bending lamp is incorporated into the outer part of the headlamp assembly and shares the same housing and reflector as the side lamp. The design of the lens projects a spread of light from the vehicle at approximately 45 degrees to the vehicle axis.

The static bending lamp uses a 35 W Halogen H8 bulb which locates in a holder which is connected via wires to the main connector on the headlamp housing. The holder is located in an aperture in the headlamp housing and rotated to lock. The bulb is accessible via a removable cover at the rear of the headlamp housing.

AFS Control
The static bending lamps operate with a steering angle sensor CAN signal which is received by the AFS control module and the LCM. The AFS control module sends a static bending lamp on request to the LCM which activates the static bending lamp bulb.

When the operation parameters of the lamp are reached, the LCM illuminates the static bending lamp bulb on using a full power PWM voltage. When the lamp is switched off, the LCM fades the bulb off by decreasing the PWM voltage in a linear manner depending on steering angle and vehicle speed.
