PROBLEM TO BE SOLVED: To provide a vehicle lighting appliance which can suppress the erroneous lighting of a light emitting element caused by noise.SOLUTION: A vehicle lighting appliance has an LED 11 connected between a power supply line L1 and a ground line L2, a capacitor C1 connected to the LED 11 in parallel therewith, and a resistor R1 connected to the LED 11 in parallel therewith. Forms of current passages of the power supply line L1 and the ground line L2 are defined according to a shape and a base board length of a printed base board, and a length of a wiring harness, and the shape and the base board length of the printed base board, and the length of the wiring harness may be longer in a cabling distance due to a constriction or the like of a vehicle structure. Therefore, such a long current flow passage portion may play a role as an antenna. Here, the resistor R1 makes a current accompanied by induction electromotive power which is generated resulting from the forms of the power supply line L1 and the ground line L2 flow, and then, suppresses a current which flows in the LED 11. |
