PURPOSE: A light emitting diode(LED) driving circuit for a vehicle is provided to continuously drive normal LED by selectively forming a current path according to the abnormality of the LED parts. CONSTITUTION: A plurality of LED parts is serially connected. The LED parts emit light based on power applied from a boost circuit(10). A switching part forms a current path in order to separately drive the LED parts. A monitoring part(41, 42) monitors the voltage of the LED parts. A controlling part(50) controls the switching part based on power applied from the monitoring part. |
