What voltage is available up stream of the regulator? Using that voltage (with an additional series resistor, if needed, to drop the extra voltage) will keep the regulator output cleaner and give you a certain activation.

Theres 9-14V or so before the regulator, from a 12V 20Ah battery drawing 7.5A at peak, my circuit is only using about 60mA at peak, and <10mA at idle, which is most of its time.
