This system is called PULSELITE (R) by precise flight
( and is supposed to improve both
visibility of the aircraft and lamp life.

I have but once seen an a/c equipped with (and using :-) pulselight
and I had the impression that it was much more conspicuos than steady
landing lights. (most probably the reason all "hazard warning" lights,
be it on a police car or on an annunciator panel are blinking)

I tried to get it installed on our airline aircraft but interest in
such matters is not easy to form in an airline.....
