PROBLEM TO BE SOLVED: To provide a vehicular lighting device capable of achieving both a lighting function and an effective illumination performance while sharing a light source.SOLUTION: A vehicular lighting device 10 attached to a vehicle includes: a light emitting diode 50 for emitting light; a light emission part 44 for illuminating a foot part, etc. of a driver's seat by emitting the light by the light emitting diode 50 as an illumination light L_l; and an illumination emission part 33 for displaying an illumination by emitting the light by the light emitting diode 50 as a decorative illumination light L_i in a direction different from the direction of the illumination light L_l. A transmission reflection part 41 provided to a second housing member 40 divides a light source beam L_s of the light emitting diode 50 into a first light L_1 travelling to the light emission part 44 and a second light L_2 travelling to the illumination emission part 33. |
