Abstract
When a turn synchronization signal stays high, and a sequential turn-on prohibition signal is negated, the first lamp unit sequentially turns on a plurality of first light emitting elements, and after completion of turning-on of the plurality of first light emitting elements, then transmits a turn-on instruction signal to the second lamp unit. When the turn synchronization signal stays high, and the sequential turn-on prohibition signal is asserted, the first lamp unit turns on the plurality of first light emitting elements at a time, and transmits the turn-on instruction signal to the second lamp unit. The second lamp unit turns on the second light emitting element, in response to the turn-on instruction signal.
