1. A vehicular lamp comprising:

  • a semiconductor light source;

    switching means connected to the semiconductor light source in series for adjusting a current flowing through the semiconductor light source by on/off operation; and

    current control means for detecting the current flowing through the semiconductor light source and controlling the current supplied to the semiconductor light source according to a detected current value,wherein the switching means is arranged to switch between a first lighting mode, in which the semiconductor light source stays on, and a second lighting mode, in which the semiconductor light source repeatedly turns on and off, andwherein the current control means is arranged to provide control such that a peak current flowing through the semiconductor light source in the second lighting mode is smaller than that in the first lighting mode.
