An LED driving apparatus group in which first and second LED groups are connected in series is provided. The apparatus includes a voltage input unit that receives an input voltage from a vehicle power device and a current controller that generates a current with a predetermined level by adjusting the received input voltage and provides the current to an input terminal of the first LED group. A first feedback path feeds back a voltage applied to a first node, which is connected to an output terminal of the first LED group, to an input terminal of the current controller. A first switching unit is disposed on the first feedback path and is switched on or off based on a control signal. A second switching unit is disposed between an output terminal of the second LED group and ground and is switched on or off based on the control signal.
