That momentary flash is also useful as an aid to passing trucks. It is their practice to flash their headlights at each other when one truck passes a slower one. The truck being passed flashes his/her headlights when the passing truck's last trailer is far enough past his nose to allow the passing truck to come back safely into the right lane. I imagine it it difficult to gauge how long your trailer(s) are using just the mirrors on a big rig, especially when you are on a busy interstate. There are lots of impatient drivers who have no idea of what a trucker can see, etc. I've seen them swoop impatiently into the right lane to go around a passing truck...trapping that truck in the left lane and risking getting smooshed if they happen into a blind spot in the trucker's mirrors. Truckers seem to appreciate your 'flash' and will blink their running lights in return for your courtesy 'all clear' signal.
