Abstract
A vehicle light can improve the visibility (noticeability) for pedestrians, roadside obstructs, other vehicles and the like in actual traffic environments. The vehicle light can be configured to project light beams with a predetermined white color, and can include a light source with a color temperature range of 4500 K to 7000 K. The light source emits light beams including four color light beams represented by four coordinate values of predicted colors including red, green, blue and yellow in the a* b* coordinate system corresponding to the CIE 1976 L*a*b* color space. The four coordinate values in the a* b* coordinate system can be encompassed by respective circle areas having a radius of, for example, 5, and each having center coordinate values of (41.7, 20.9) for red, (−39.5, 14.3) for green, (8.8, −29.9) for blue and (−10.4, 74.2) for yellow, for example.
