A two-stage temperature gauge for a vehicle indicates whether engine temperature is normal or overheated. The gauge registers "normal" when the vehicle engine temperature is at or below a threshold value and registers "hot" when the vehicle engine temperature exceeds the threshold value. A circuit (10) for operating the gauge has an input terminal (12) for receiving a signal from an electronic engine controller (14) representative of engine temperature for causing the gauge register either "normal" or "hot". An indicating lamp (28) connected to the input terminal (12) illuminates to also indicated an overheated engine condition.
