1. A vehicle switch illumination device comprising:
a rotator that includes a pointer indicator and is operable by rotation;
a first light source;
a second light source disposed adjacent to the first light source; and
a light guide that includes a light incident surface through which light enters, the light guide guiding the light that enters through the light incident surface to the pointer indicator, wherein
the light guided by the light guide exits through the pointer indicator,
the light guide rotates in accordance with rotation of the rotator such that a position of the light incident surface changes in accordance with the rotation of the rotator, and
the rotator rotates the pointer indicator between a first position in which the light incident surface faces the first light source and a second position in which the light incident surface faces the second light source.
