Abstract
A meter unit includes pointer light sources, main mark light sources, and sub-mark light sources. The pointer light sources, the main mark light source, and the sub-mark light sources are turned on with time lags after an ignition (IG) switch is turned to an ON position. Therefore, pointers, main marks, sub-marks of the meter unit are illuminated with time lags. This makes outlines of the pointers, the main marks, and the sub-marks sharp. As a result, not only the pointers but also the marks and the sub-marks of the meter unit outstand from each other.
