A headlight includes a low-beam lamp arranged on a longitudinally extending center line of a vehicle body and left and right high-beam lamps arranged on the opposite sides of the low-beam lamp as viewed in plan. This arrangement permits the total reflection area of the reflecting portions of the left and right high-beam lamps can be increased. The lens of the low-beam lamp and the left and right high-beam lamps is integrally formed and largely curved toward the front side of the vehicle body, thereby suppressing an increase in the air resistance by the headlight. Accordingly, the brightness of the headlight can be increased without changing the rated powers of the bulbs of the low-beam lamp and the high-beam lamps. Further, by symmetrically arranging the left and right high-beam lamps with respect to the low-beam lamp, the illumination condition on the road surface by the high beam in the case of cornering to the left can be made similar to that in the case of cornering to the right.
