<P>PROBLEM TO BE SOLVED: To improve visibility in a specific direction. <P>SOLUTION: A vehicular warning light includes a first light source arranged on a designated rotary axis, at least one second light source arranged on a designated axis crossing the rotary axis, an optical member rotated around the rotary axis and irradiating in a designated direction by controlling light emitted from the first light source and light emitted from the second light source, and a rotation drive section for making the optical member rotate around the rotary axis. Accordingly, the light emitted from the first light source and the second light source is controlled by the rotating optical member, and visibility of the light in a specific direction where the second light source is arranged can be improved since luminance in the direction where the second light source is arranged becomes high. <P>COPYRIGHT: (C)2012,JPO&INPIT |
