Vehicular lamp system for automotive vehicle

A first reflector (11201), equipped with a light source, and a second reflector (11202) are each able to deflection a reflection direction thereof toward a vehicular turn direction independently of the other. A driving section (2) that operatively performs a deflection drive for the first and second reflectors is controlled by a controller (3) on the basis of the outputs of a vehicular velocity detector (6) and a vehicular steering angle detector (5) in such a manner that the second reflector (11202) is deflected toward the vehicular turn direction according to the detected steering angle when the detected vehicular velocity falls in a low velocity range and that the first reflector (11201) is deflected toward the vehicular turn direction according to the steering angle when the detected vehicular velocity falls in a high velocity range.
