To attain a lightweight vehicular lighting fixture and to improve its heat dissipation.
This vehicular lighting fixture 1 is composed of a first unit 10 and a second unit 20. The units 10, 20 have heat sinks 17, 23 respectively, and the heat sinks 17, 23 have pedestals 17a, 23a and heat dissipating fins 17b, 23b. The pedestals 17a, 23a are vertically and horizontally extended, and light sources 11, 21 are provided on the pedestals 17a, 23a. The heat dissipating fins 17b, 23b are flat plates extending frontward. backward and vertically on the pedestals 17a, 23a. Since the pedestals 17a, 23a and the heat dissipating fins 17b, 23b are thus structured, heat discharged from the heat dissipating fins 17a, 23a is smoothly exhausted upward without staying in the heat sinks 17, 23.
