Glow Plug Indicator Symbol

Glow Plug Indicator SymbolThis is the Glow Plug Indicator symbol. Diesel engines require heat in the cylinders to operate, which is supplied by glow plugs when the engine is cold. This light will be illuminated when the ignition is turned on until the plugs are heated sufficiently to start the engine. The image will look like a coil or loops in amber or yellow.
