Our dusk sensors detect light levels and automatically turn on the headlights when the light is low, helping you to drive more safely.
The dusk sensor system is fitted close to the rain sensor, behind your internal mirror. It detects light levels and automatically turns on the dipped headlights when the levels are low - for instance, when you are driving through a tunnel, at night, or when dusk sets in. Your headlights must be switched on to auto setting for the dusk sensors to work. They turn off automatically once you're back in the light.
