Flashing light control system

The method involves dividing light surface areas (FB) illuminated by the flashing light into vertical sub-areas in the form of columns (S1-Sn). The columns at a lateral distance from each other in the defined direction of travel other sequentially adopt the ON state. An activated column remains active until all other columns are activated in succession, then the process starts again from the beginning. AN Independent claim is also included for the following: a flashing light for implementing the method.
