In a vehicle front lighting apparatus, the number of switch elements brought into an opened state and an applied voltage value is detected every time a predetermined detection condition is satisfied, the amount of change from the number of switch elements detected last time and the amount of change from the voltage value detected last time are acquired, and it is determined that a disconnection has occurred if the amount of change in the number of switch elements does not match the amount of change in the voltage value.
