AS for the life of the bulb, "pathBlazer uses a soft-switching technique. It throttles the current flow through the bulb filament, so that there's no "thermal shock" due to a sudden inrush of current, which can damage the bulb filament or shorten its life considerably. This is far superior than maintaining a small voltage!" and pathBlazer circuit modulates the hi-beam current - from 100% ON to about 17% OFF. This is accomplished by using a p-channel MOSFET, which is inherently safe. The MOSFET is designed to fail in the ON state. For additional safety, the circuits DO NOT utilize the lo-beam whatsoever!
So for Aus, not sure if it translates to a flash as it modulates by a 17% drop which more of a pulse, nothing even like switching from hight o low beam, I believe.
