Abstract:
To provide a vehicle lighting device and a vehicle lighting fixture capable of alleviating rapid rise in a current value even when a film-state resistance is partially removed.SOLUTION: A vehicle lighting device includes a socket and a light emitting module provided on one end unit side of the socket. The light emitting module includes: a substrate 21; at least one light emitting element 22 provided on the substrate 21; and a resistance 23 serially connected to the light emitting element 22 and having a slit 23i. In a plan view, the resistance 23 has: a first side 23a; a second side 23b facing the first side 23a; a third side 23c intersecting with the first side 23a and the second side 23b; and a fourth side 23d facing the third side 23c. Distance L2 between the slit 23i and the fourth side 23d becomes smaller as going from the first side 23a to the second side 23b.SELECTED DRAWING: Figure 5
