1. A light emitting diode (LED) package for a lamp of a vehicle, comprising:a printed circuit board (PCB);
an LED circuit unit including an LED chip, a zener diode, a thermistor, and a resistor mounted on the PCB, each of the LED chip, the zener diode, the thermistor and the resistor comprising first and second terminals for electrical connection;
a connector for connecting the LED circuit unit to at least one battery of the vehicle and to a common ground of vehicle body, the connecter comprising a first pin, a second pin, a third pin and a fourth pin;
a first wire connecting the first pin or the connector to the first terminal of the LED chip;
a second wire connecting the second pin of the connector to the first terminal of the thermistor;
a third wire connecting the third pin of the connector to the first terminal of the resistor; and
a fourth wire connecting the fourth pin of the connector to the second terminal of each of the LED chip, the thermistor and the resistor via their second terminals,
wherein the first, second, third and fourth wires are not electrically connected to each other on the LED package such that the fourth pin provides a common ground connection for all of the LED chip, the thermistor and the resistor.
