Very simple idea, however I'd buffer the LED using a CMOS 4049 inverter or
possibly a 4011 quad nand wired as an inverter, as it accomplishes the same
thing, but doesn't allow the LED to draw ANY current off the injector.
Prolly wouldn't make a difference, but why waste current :)

Just a thought.

As far as using a meter, obviously an analog meter would be better, as the
response to things would be slower than a digital, even though digital
meters display every 1/4 or 1/8 of a second.  Just something about a needle
that I still like :)
