Classification: CPC B  F  H | IPC B  F  H

Claim 0:
1. A vehicle lighting device, comprising:
a socket;
a substrate provided on one end side of the socket;
a first circuit provided on the substrate; and
a second circuit provided on the substrate,
wherein the first circuit has:
a plurality of first light emitting elements; and
a control element electrically connected to the plurality of first light emitting elements and controlling a value of a current flowing through the plurality of first light emitting elements,

wherein the second circuit has:
second light emitting elements the number of which is smaller than the number of the plurality of first light emitting elements; and
a resistor connected in series to the second light emitting elements,
wherein the control element detects an input voltage and changes the number of the first light emitting elements through which the current flows according to the input voltage detected.
