It may not be impossible, but it might be difficult. I'd have to think about it, or get one of the engineer types here to think about it. From what I've found, that light doesn't work like typical lights, with power on one side and ground on the other. It gets 12 volts from the regulator on one side, and 12 volts from the battery on the other. As long as those voltages are equal, or nearly so, there is no difference in potential, so the light stays off. But when one of those voltages strays away from the other, it creates a difference of potential and the lamp lights up. I don't know if it's incandescent or LED. If it's incandescent, the brightness level will probably vary as the difference in potential changes. If it's LED, there would need to be a threshold met before it lit up. In short, it doesn't work on the presence or absence of voltage, but on the difference between two voltages. Skyview typically looks for the presence or absence of voltage as indications, and the general purpose pins have a constant bias voltage applied, so It would take some thought, and effort, to make them play well together. Maybe a tap off a parallel voltage divider?
