PROBLEM TO BE SOLVED: To enable to prevent effectively from impressing an excessive voltage on a stabilizer even if the level of supply voltage changes. SOLUTION: As for a stabilizer device 1 with a stabilizer 2 for a discharge lamp 3 having a plurality of input terminals 2A, 2B at the input side, a voltage sensor 7 for detecting the level of supply voltage to the stabilizer device 1 of a fishing light and a main relay 5 for connection switching so that the supply voltage may be connected to any one of the plurality of input terminals 2A, 2B are provided, and according to the output of the voltage sensor 7, an auxiliary relay 6 is controlled and supply voltage is impressed on the input terminal corresponding to the level of supply voltage out of the plurality of input terminals 2A, 2B. Thereby, even if the level of supply voltage changes, following this, the supply voltage can be impressed on the input terminal which corresponds to the supply voltage, out of the input terminals of the stabilizer 2, therefore impression of excessive voltage on the stabilizer 2 can be prevented effectively.
