The light coming on or not is regulated by the little circuit board that
it's mounted on inside the gauge (it's designed to come on at power-on and
any time the gauge sender line falls below the voltage on a 5.1V zener
diode on that circuit board, and stay on at least two seconds every time it
comes on).  But whether it blinks or not is irrelevant, because the LED
itself as originally installed in the gauge is a five-volt self-blinking
LED, i.e. it has a blinker chip embedded in the epoxy in series with the
actual LED chip.  Either the blinker chip has failed in the ON position or
someone has replaced the LED with a non-blinking version.
