I disagree, 100mA will light up most test lights bright!I suppose it could, but it wouldn't be very hard to bypass. It's just going to disconnect the PD box or somesuch or it will be prohibitively expensive to install. Or else it just disconnects one critical system like the ignition primary or the fuel pump.
But a REALLY easy way to tell is to disconnect that alarm and crank the vehicle (with a jumpstart if need be).
I strongly discourage using a test light for this because it isn't a terribly sensitive test. Use an AMMETER, preferably the clamp-on type. If you had two 500 mA drains, you wouldn't be able to find them with a test light, but it would be obvious with an ammeter.
