VEHICLE LED LIGHTING DEVICE SYSTEM

摘要

The present invention relates to an LED lighting device system for a vehicle which prevents erroneous lighting of the LED lighting device due to leakage current at the operation switch. An LED lighting device system (80) for a vehicle is provided with an LED lighting device (X) having an LED light source (84), an operation switch (32) for lighting and extinguishing the LED light source (84), and a power source (66) that is connected to the input side of the operation switch (32) and feeds electrical current to the LED light source (84). The LED light device system (80) for a vehicle has a switching element (100) capable of blocking electrical current flowing to the LED light source (84) and a detection unit (104) that detects voltage on the output side of the operation switch (32) and causes the switching element (100) to block the electrical current.
