The primary intent of the engine glow plug light, which is most of the time represented by a yellow coil, is to make sure that your glow plugs are working correctly. Indeed, it must light up when you switch on your Honda Insight to tell you that they are heating the intake air in your cylinders and must go out after a few minutes when the engine is running. This preheat light is therefore not meant to stay or come on while driving with your motor vehicle.
