1. A light module used for a lighting tool for vehicles, comprising:
a first light function provided on an upper surface of a heatsink;
a second light function provided on a substrate which is separate from the heatsink;
wherein
the first light function is such a function that generates a larger amount of heat by lighting than the second light function,
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, the heatsink dissipates heat generated from the first light function, without through the substrate and dissipates heat generated from the second light function through the substrate, and the first light function and the second light function are positioned substantially at a same height in a perpendicular direction.
