PURPOSE:To obviate traveling with a high beam in the day time by comprising a lighting circuit for performing the low beam lighting of head light preferentially and performing the high beam lighting with a switching operation. CONSTITUTION:A light system 6 comprises a lighting circuit 7, loads 8 such as a tail light and a meter light, and a head light 9. At a travelling time of a motorcycle at day time, when a light switch RS is operated, a switch armature S2 is preferentially connected to a DL position P2 for lighting at day time, and the head light 9 is, thereby, lighted with the low beam. Consequently, so far as the light switch RS is not operated to connect the armature S2 to an ON position P3 and connect an armature S3 of a dimmer switch DS to a high beam position P8, the high beam lighting is not performed. The travelling with the high beam in the day time can be effectively obviated. |
