<p><P>PROBLEM TO BE SOLVED: To provide a controller for a vehicular lamp which can assist an operation of a broken driving circuit by an operation of the other driving circuit even if one of a brake lamp driving circuit 13a and a tail lamp driving circuit 13b gets out of order. <P>SOLUTION: In the case that a stop signal indicates H and where a brake lamp lighting signal indicates L, it is determined that the brake lamp driving circuit 13a gets out of order. In the case that the stop signal is inputted into the tail lamp driving circuit 13b, tail lamps 11R and 11L are lit at high luminance by a lighting control function of the tail lamp driving circuit 13b, and operated equivalently to brake lamps 12R and 12L. Consequently, even in the case that the brake lamp driving circuit 13a gets out of order, the tail lamps 11R and 11L can be operated in substitution for the brake lamps 12R and 12L. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
