The present invention accurately detects the illumination on the surface of an instrument panel, to thereby enable an easy view of the instruments. A meter unit includes an instrument panel in which a speedometer and other instruments are arranged, and an information display panel for displaying various information by characters and other graphic symbols. The instrument panel has a translucent dial, on the back side of which illuminating lamps are installed. A light sensor is located in the speedometer adjacent to indicators which display various kinds of information. Since the actual illumination on the instrument panel can be accurately detected in accordance with a result of detection by the light sensor, the luminance of the illuminating lamp can be controlled on the basis of the result of the detection, to thereby provide proper illumination for the rider's easy view of the instruments. |
