Function: A glow plug indicator is a device that signals when the glow plugs are ready to ignite the fuel-air mixture in the engine. It usually lights up when the ignition is turned on and goes off when the glow plugs are hot enough. This helps to start the engine more easily and smoothly in cold weather.
