You possibly mean the glow plugs and if they stay on then probably the relay or switch is stuck on. If it is a choke light which stays on you don't have a choke so it's either a wiring fault or it is being powered some other way.

You might have an auto cold start device which alters the fuel and timing, this normally resets itself when the engine warms up unlike a manual type with a pull knob similar to a choke. This could be a thermostat or a fuel pump fault. If your engine is noisey then it could be too far advanced and the problems may be linked.
