In a driving assistance apparatus, an object detecting unit detects an object that is present in a periphery of an own vehicle based on an image captured by an imaging apparatus provided in the own vehicle. An avoidance control unit performs collision avoidance control for avoiding a collision between the detected object and the own vehicle when a collision between the object and the own vehicle is likely. A light distribution control unit switches irradiated light of an irradiation apparatus provided in the own vehicle between high beam and low beam based on a predetermined switching condition. The light distribution control unit performs switching suppression control to suppress switching of the irradiated light from high beam to low beam while the avoidance control unit is performing collision avoidance control in a case where the irradiated light is set to high beam.

A lighting circuit turns on multiple semiconductor light sources. Multiple current sources are each coupled in series with a corresponding one from among the semiconductor light sources. A switching converter supplies a driving voltage V.sub.OUT across each of multiple series connection circuits formed of the multiple semiconductor light sources and the multiple current sources. A converter controller controls a switching transistor of the switching converter based on a relation between a voltage across one from among the multiple current sources and a reference voltage having a positive correlation with the temperature T.sub.j.

A vehicle lamp includes a turn signal lamp, a daytime running lamp, and a position lamp. A first driving circuit drives a first light source that is the turn signal lamp.
