PROBLEM TO BE SOLVED: To suppress a decrease in lumen maintenance factor of organic EL, in a vehicular lighting device that comprises a light emission part using a light-emitting diode and the like as a light source and a light emission part using an organic EL element as a light source.SOLUTION: A vehicular lighting device 10 includes a first light emission part 12, and a second light emission part 14 using an organic EL element as a light source. The second light emission part 14 is lit when a tail lamp is in an ON-state, and both the first and second light emission parts 12 and 14 are lit when a stop lamp is in an ON-state. The vehicular lighting device 10 also includes an extinction part 24 that makes light intensity of the second light emission part 14 in the ON-state of the stop lamp lower than in the ON-state of the tail lamp.SELECTED DRAWING: Figure 6 |
