Highly unlikely, it will need to act as a transformer and the LED will
require far more current to illuminate than simple paralell induction will
induce.  Also if this were the case the problem would be more prominent if
the engine were on as the amplifier would be receiving more voltage and
would have greater headroom.  I vote for a big voltage drop at the alarm
module causing a hickup that flashes the lamp.
