Abstract

PURPOSE:To prevent a drive from feeling an abnormality in a method of driving a lamp rotating around the optical axis in order to change the direction of illumination of lamp units in association with manipulation of a steering unit, by rotating only a lamp unit which is outside in the turning direction of a vehicle body without rotating a lamp unit which is inside in the same direction. CONSTITUTION:Lamps 1L, 1R rotating around their optical axes, are illumination lamp units are rotated by a stepping motor or the like in its entirety so as to direct their optical axes left and right. The lamps 1L, 1R illuminate in the front direction of the vehicle 20 by means of control units 2 incorporated therein in the case of no manipulation of a steering wheel 21, with no reciprocation for corrective operation. Further, the drive for the lamps L1, L2 is carried out only for the one which is outside in the turning direction of a vehicle. Accordingly, the illumination is made in the advance direction of the vehicle so as to improve the visibility, and the illumination in front of the vehicle 20 is carried out, thereby it is possible to prevent the driver from feeling an abnormality.
