It is desirable that light functions such as a daytime running lamp, a positioning lamp, and a turn indicator lamp each take an optimal heat dissipation structure. A first light function and a second light function for executing light functions such as a daytime running lamp, a positioning lamp, and a turn indicator lamp are executed by LEDs each including a light source, protection resin, and a light source plate. An LED for the first light function is provided on an upper surface of a heatsink, and an LED for the second light function is provided on a substrate separate from the heatsink. The substrate is mounted at a position on the upper surface of the heatsink so that the first light function and the second light function are respectively performed.
