Talking about the little curly thing signal??? Because it comes on all the time here in florida usually for like 1-3 seconds.
The Wait to Start light comes on every time you turn the key to the on position, if the ambulant temperature is above about 60 degrees it will go out with the rest of the lamps after the lamp test.
If the ambulant temperature is below about 60 degrees it will stay on for anywhere from about 15 seconds to 30 seconds. This allows the Grid heater in the Air intake to get hot, to heat the incoming air so the truck will start easy without a bunch of white smoke.
