ABSTRACT:
An apparatus and method for controlling cross-walk boundary lighting, such as multiple flush-mounted lights on the boundary, or boundaries, of a cross-walk. Enhanced flashing patterns are output in a primary output to drive cross-walk lighting to produce a different output pattern with each cross-walk activation. Enhanced flashing patterns comprise the output of multiple pulses of light (e.g., 2 to 5) with various pulse widths and timing during the ON portion of the light cycle. Selection is performed from a plurality of enhanced flashing patterns retained within a cross-walk lighting controller. One or more secondary outputs are configured to generate other patterns, in particular an output with a field selectable relationship and synchronization to the primary pattern, such as a matching pattern, a non-enhanced version, a non-enhanced complementary pattern, or a solid output for as long as the primary output is active.
