The transmission unit 104 transmits the received unique digital definition value to the navigation unit 105 through a wired or wireless transmission method.

The navigation unit 105 receives a unique digital definition value for the red wavelength signal detected by the brake lamp from the transmission unit 104 through a predetermined method.

At this time, the angle setting value of the first sensor unit 101 by the user increases as the distance between the traffic light close to the user's vehicle and the first sensor unit 101 is closer.
