Rain-Light Sensor For Automatic Driving Lights Control

The rain-light sensor measures the ambient light conditions outside the vehicle.

• As it starts to get dark, the rain-light sensor sends the message "Twilight" to the light module. The light module informs the adaptive headlights control unit so that the automatic headlight-range adjustment of the dipped-beam headlights can be activated. The headlights are tilted up and down as required, but they are not yet swivelled towards the bend in the road.
• In darkness, the rain-light sensor sends the message "Darkness" to the light module. The light module sends the relevant information to the adaptive headlights control unit.

The headlights are swivelled as necessary.
