　第１のセキュリティーインジケータ１３ｂは、例えば、運転者が車の起動スイッチ等を押して車両の電源を切ると点滅する。第２のセキュリティーインジケータ４１は、第１のセキュリティーインジケータ１３ｂが点滅中に、キーレスエントリーシステム(ｋｅｙｌｅｓｓ　Ｅｎｔｒｙ　Ｓｙｓｔｅｍ)等で、リモコンにて車のドアがロック（施錠）されると点滅する。 The first security indicator 13b blinks, for example, when the driver presses the start switch of the vehicle or the like to turn off the power of the vehicle. The second security indicator 41 blinks when the car door is locked (locked) by the remote controller by a keyless entry system (keyless entry system) or the like while the first security indicator 13b is blinking.
　但し、第２のセキュリティーインジケータ４１は、ライト消し忘れ状態、半ドア状態（ドアが閉まっていない状態）、パーキングギヤへの入れ忘れ状態等、不正常な状態でドアがロックされた場合は点滅しない。尚、第１のセキュリティーインジケータ１３ｂと第２のセキュリティーインジケータ４１は、不正常な状態（異常な状態）でドアがロックされた場合は、正常状態での点滅よりも早いタイミングの点滅であってもよい。 However, the second security indicator 41 does not blink when the door is locked in an abnormal state such as a state where the light is forgotten to be turned off, a half-door state (a state where the door is not closed), or a state where the door is forgotten to be put in the parking gear. When the door is locked in an abnormal state (abnormal state), the first security indicator 13b and the second security indicator 41 may blink at an earlier timing than the blinking in the normal state. Good.
　第２のセキュリティーインジケータ４１は、リモコンにて車のドアがアンロック（開錠）されると消灯する。第１のセキュリティーインジケータ１３ｂは、車両の電源を入れると消灯する。 The second security indicator 41 turns off when the car door is unlocked (unlocked) by the remote control. The first security indicator 13b turns off when the vehicle is turned on.
　このように形成されることにより、背面部１０５に発光可能な第２のセキュリティーインジケータ４１が設けられるので、車両の前方の広範囲から容易に第２のセキュリティーインジケータ４１を視認可能となり、十分な犯罪抑止効果を期待できる。 By being formed in this way, since the second security indicator 41 capable of emitting light is provided on the back surface 105, the second security indicator 41 can be easily visually recognized from a wide range in front of the vehicle, and sufficient crime deterrence is achieved. The effect can be expected.
　また、不正常な状態でドアがロックされた場合は、第２のセキュリティーインジケータ４１が点滅しないので、車両の運転者等への異常の検知力を向上することができる。 Further, when the door is locked in an abnormal state, the second security indicator 41 does not blink, so that the ability to detect an abnormality to the driver of the vehicle can be improved.
