PROBLEM TO BE SOLVED: To provide a lighting fixture lighting circuit for vehicle capable of suppressing dazzle when a semiconductor type light source is lit or lit out.SOLUTION: A lighting fixture lighting circuit 1 for vehicle comprises: semiconductor type light sources LD1, LD2, LD3 used for lighting a vehicle; and light adjustment means 2 for adjusting amount of light emitted by the semiconductor type light sources by generating power source in which potential changes gradually and supplying to the semiconductor type light sources. The light adjustment means 2 raises the potential from zero potential to predetermined potential during lighting of the semiconductor type light sources, to raise light emission of the semiconductor type light sources from a zero light amount to a predetermined light amount gradually. |
