A lighting unit for a motorcycle for efficiently cooling heat generated from an LED apparatus. An LED lighting unit includes two plate-like members on which LED apparatus are mounted as light sources. Reflectors are disposed so as to cover the LED apparatus and configured to reflect irradiation light from the LED apparatus forwardly of the vehicle body. The two plate-like members are disposed in an opposing relationship to each other with a space provided therebetween such that mounting faces of the LED apparatus are directed to the outer sides. Cooling fins are provided on the two plate-like members in such a manner so as to extend in an opposing relationship to each other toward the space. The cooling fins are disposed such that a longitudinal direction thereof is perpendicular to a longitudinal direction of the two plate-like members. The plate-like members and the reflectors are formed separately from each other.
