Abstract: A vehicle front lighting apparatus includes a lighting device array in which multiple lighting devices are connected in series, multiple bypass circuits, multiple switch elements, a lighting intensity detector, a lighting schedule generator, a lighting controller, a current value detector, a voltage value controller, a detector, and a disconnection determiner. When there is the switch element to be brought into a closed state during a prohibition period from a lighting timing to a post-lighting timing, the lighting schedule generator changes a timing at which the switch element is brought into the closed state outside the prohibition period. The disconnection determiner determines that a disconnection has occurred in any of the bypass circuits when the number of switch elements detected at the post-lighting timing does not match a voltage value.

Abstract: 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.

Abstract: A vehicle front lighting apparatus includes a lighting device array in which a plurality of lighting devices are connected in series, a plurality of bypass circuits, a plurality of switch elements, a lighting controller, a current value detector, a voltage value controller, and a disconnection determiner. The voltage value controller applies a voltage to the lighting device array, and controls a voltage value to be applied to cause a value of current flowing through the lighting device array to reach a predetermined target current value. The disconnection determiner determines that there is a disconnection in any of the bypass circuits when the number of the switch elements brought into the opened state does not match the controlled voltage value.

Abstract: A wiring module for electrically connecting a plurality of electric parts disposed on an equipment frame to a source of electric power, the module comprising an elongated insulating substrate formed to extend along a path adjacent to electric parts disposed on the frame. A pattern of wiring conductors extends along and integral with the insulating substrate for conducting electric current from the source of electric power to each of the electric parts to be connected. The insulating substrate has one or more edge portions provided with protrusions integrally formed with the substrate and extending laterally therefrom. The protrusions each are positioned on the insulating substrate at a location adjacent an electric part to be connected and at least a portion of the wiring conductors are integral with the protrusions to provide a contact on the protrusions for connection to corresponding electric parts.
