Lighting apparatus disposition structure for saddle riding vehicle

A saddle riding vehicle, comprising:

• a vehicle body frame including a head pipe defining a steering axis for a front wheel, a pivot shaft supporting a rear wheel through a rocking member, left and right main frame members, left and right pivot frames for supporting the pivot shaft, a seat, and left and right seat frames for supporting the seat;
• a vehicle body cover at least partially covering the vehicle body frame;
• a light source unit including a laser light source, a driving unit for driving the laser light source to emit light, a heat sink thermally coupled to the laser light source for dissipating heat generated by the light source unit, and a plurality of cooing fins extending from the heat sink and cooled by air flowing through a gap provided between the vehicle body frame and the vehicle body cover, the light source unit being disposed between the left and right main frame members and between the rocking member and the seat;
• a light guide unit including at least a first light guide member with a first input end optically coupled to the light source unit and extending forwardly from the light source unit along an inner side face of one of the left and right main frame members to a first output end at toward a front side of the saddle riding vehicle, and a second light guide member with a second input end optically coupled to the light source unit and extending rearwardly from the light source unit along an inner side face of one of the left and right seat frames to a second output end at a rear side of the saddle riding vehicle and
• at least two light emission units, each coupled to the first and second output ends of a respective one of the first and second light guide members.
