Abstract

An LED lighting device system for a vehicle prevents erroneous lighting of the LED lighting device due to leakage current at fee operation switch. An LED lighting device system for a vehicle is provided with an LED lighting device having an LED light source, an operation switch for lighting and extinguishing the LED light source, and a power source that is connected to the input side of the operation switch and feeds electrical current to the LED light source. The LED light device system for a vehicle has a switching element capable of blocking electrical current flowing to the LED light source and a detection unit that detects voltage on the output side of the operation switch and causes the switching element to block the electrical current.
