【実用新案登録請求の範囲】[Scope of utility model registration request] 車両に装着された複数のランプにおける１個のランプの
断線を検出電圧と基準値と比較して検出し警告を発する
自動車のランプ断線検出装置において、電源電圧の変動
に対し前記基準値を複数段のステップ状に変化させる手
段を備え、電源電圧の変動に対する検出範囲を広げ得る
ようにしたことを特徴とするランプ断線検出装置。In an automobile lamp breakage detection device that detects the breakage of one lamp among a plurality of lamps installed in a vehicle by comparing the detection voltage with a reference value and issues a warning, the reference value is set in multiple stages in response to fluctuations in power supply voltage. What is claimed is: 1. A lamp breakage detection device characterized by comprising means for changing the voltage in a stepwise manner so as to widen the detection range for fluctuations in power supply voltage.
