  However, in the case of these vehicles, each lamp is visible only from one of the front and rear of the vehicle, so in order to obtain the lighting effect of the lamp on the front and rear sides of the vehicle, And a rear lamp must be installed in the vehicle. For this reason, there is a concern that the number of lamps installed in the vehicle increases, leading to a rise in manufacturing cost and an increase in weight. Further, in the above-mentioned vehicle equipped with a lamp body, the lamp body has no function of recognizing the vehicle body itself (vehicle width, etc.).

  For small vehicles, etc., when a vehicle with a high driving viewpoint such as a large truck or trailer (hereinafter referred to as a “high-viewpoint vehicle”) approaches from behind, the driving of the high-viewpoint vehicle in which the vehicle body looks closely at the front. Visibility tends to decrease by entering below the visual field of the person. In such a situation, the alerting effect of a lamp such as a brake lamp provided at the rear end of the vehicle body is not always sufficient. For this reason, at present, it is desired to devise means capable of causing a driver of a high-viewpoint vehicle to recognize the vehicle with certainty.

  Therefore, the present invention enables recognition of lighting in front and side of the vehicle and recognition of lighting in the rear of the vehicle with a common lamp, and reduces the number of parts and enhances alerting by lighting the lamp. An object of the present invention is to provide a vehicular lamp that can be used.
