Diesel-Powered Car Light Symbols

Vehicle Diesel-Powered Light Symbols

A common car light symbol on the dashboard of diesel-powered vehicles is the Glow Plug Indicator – it comes on when the engine’s glow plugs are still warming up and your engine should not be started until this light goes out – if it flashes after starting the engine, an issue has been detected and a glow plug may have worn out. Below is a list of more dashboard lights specific to diesel vehicles.
