quick-flashing light

[] In signal lighting: A single flashing light repeated at a frequency equal to or greater than one Hz. There is no agreed-upon verbal differentiation between lights that flash at one Hz and those that flash more rapidly.

A quick-flashing light may be a sequence of single flashes or a sequence of multiflick flashes, at one-second intervals. There is no restriction on the ratio of the duration of the light period to that of the dark period.
