  "textContent": "A method for operating vehicle lights and a light sensor are provided. A capacitive light sensor (4226) is configured to sense a presence and intensity of light over at least three wavelength, with each said wavelength being associated with a respective output channel of the light sensor. A buffer is filled with data from output channels, with the buffer being filled with a predetermined number of data points at a predetermined frequency. An edge change is detected in the data in the buffer. An on/off state (4102, 4106) of the vehicle lights is maintained when an edge change is not detected. The method comprises the steps of determining a speed of the vehicle to adjust thresholds, correlating edge changes in at least two of the first, second, and third channels; and changing the on/off state of the vehicle lights in dependence on the correlation.",
