Abstract
A vehicle light apparatus includes: a power consuming portion provided in parallel with a group of light emitting elements for causing a total power value including power consumed by the lamp to become a normal power value, a breakage detecting portion for detecting a breakage with respect to the group of light emitting elements, and a control portion for controlling power supply to the group of light emitting elements, wherein in the event that a breakage of the group of light emitting elements is detected by the breakage detecting portion, a power supply to the lamp including the group of broken light emitting elements is stopped or power supplied to the lamp is reduced by the control portion. By providing the power consuming portion, the load characteristic can be made constant, and power consumption can be reduced when a breakage of the light emitting element is detected.
