To provide an indicator lighting circuit capable of preventing erroneous lighting of an indicator due to the occurrence of a leakage current, and a motorcycle.SOLUTION: An indicator lighting circuit 21 receives an input voltage Vin from an in-vehicle power source 11 via an electric switch 12 in response to closure of the electric switch 12 to light a high beam indicator 28 indicating that a headlight is high beam. The indicator lighting circuit 21 comprises: a supply voltage detection circuit 21a which detects a supply voltage Vc of the in-vehicle power source 11; a threshold setting unit 23a which sets a threshold on the basis of the supply voltage Vc detected by the supply voltage detection circuit 21a; and a lighting control unit 23c which determines the electric switch 12 to be in a closed state to light the high beam indicator 28 if the input voltage Vin is equal to or higher than the threshold set by the threshold setting unit 23a, and determines the electric switch 12 to be in an open state not to light the high beam indicator 28 if the input voltage Vin is lower than the threshold.SELECTED DRAWING: Figure 2

    【課題】リーク電流の発生時にインジケータが誤点灯することを抑制できるインジケータ点灯回路及び自動二輪車を提供する。【解決手段】インジケータ点灯回路21は、電気スイッチ12が閉じられたときに電気スイッチ12を介して車載電源11から入力電圧Vinを受けて、ヘッドライトがハイビームであることを示すハイビームインジケータ28を点灯する。インジケータ点灯回路21は、車載電源11の電源電圧Vcを検出する電源電圧検出回路21aと、電源電圧検出回路21aにより検出された電源電圧Vcに基づき閾値を設定する閾値設定部23aと、入力電圧Vinが閾値設定部23aにより設定された閾値以上であるとき電気スイッチ12が閉状態であるとしてハイビームインジケータ28を点灯させ、入力電圧Vinが閾値未満であるとき電気スイッチ12が開状態であるとしてハイビームインジケータ28を点灯させない点灯制御部23cと、を備える。【選択図】図2
