The light (when working properly) blinks for a few seconds any time the
gauge receives a signal that would cause it to read full scale (even if the
signal is only very brief).  This happens either when the temp is too high
or when the level controller detects that coolant in the tank is low and
sends a high-temp signal to the gauge.  Depending on the controller, it's
either a continuous signal or a pulsed one that doesn't noticeably move the
needle.

Note that the owner's manual specifically says that a high gauge reading is
still normal operation unless the light is blinking as well.
