As described above, the lighting control unit 3 as a light color variable unit
In the above, the lighting lamp to be turned on is switched according to the detection result of the humidity sensor 4 serving as a weather information detecting unit, and the light color of the lighting lamp is changed. When rain or fog occurs, the rain / fog lighting lamp Pb is turned on. Like that. Since the illumination light Pb for rain / fog has a longer wavelength than the illumination light Pa for fine weather, the light of the illumination light Pa is prevented from being irregularly reflected in the fog, and the driver's view is blocked. Can be prevented. Therefore, even in bad weather, it is easier to find pedestrians and pedestrians who are crossing the pedestrian crossing, and it is possible to alert the driver to the pedestrian crossing pedestrian sufficiently, and the safety of the pedestrian crossing Can be secured.
