To provide automotive lamp equipment using a plurality of LED light emitting units for meeting regulations in one LED failure.
The automotive lamp equipment includes the plurality of LED light emitting units for driving a LED array in which one or more LEDs are arrayed in series, to emit light. The LED light emitting unit includes a failure determining circuit for determining a failure of the LED array in the other LED light emitting unit, and a switching element connected to the downstream side of the LED array in its own LED light emitting unit and adapted to be switched by the failure determining circuit. The failure determining circuit finds failure determination as a logical AND, based on the condition of the LED array in all other input LED light emitting units, and turns the switching element into an OFF state to light off the LED array in the own LED light emitting unit when determining that the LED array fails, in accordance with the logical AND.
