Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a marker lamp lighting device capable of forcibly lighting a marker lamp when normal lighting control of the marker lamp cannot be performed.SOLUTION: A lighting power source from a lighting power circuit 21 is supplied to the marker lamp 12 by bypassing a lighting control circuit 30 by bypass operation of a bypass means 33. Supply control of a lighting power source from the lighting power circuit 21 to the marker lamp 12 by the lighting control circuit 30, is made possible by bypass releasing operation of the bypass means 33. An operation control circuit 19 controls the bypass operation and the bypass releasing operation of the bypass means 33 in a switching system. A control part 29 enables the bypass means 33 to perform the bypass operation by the operation control circuit 19 when determining abnormality of operation of the lighting control circuit 30 by monitoring the operation of the lighting control circuit 30.
