Migma has recently installed two double-sided MassDOT-approved RRFB systems at one crossing in Massachusetts. In this installation, two standard pushbuttons with FCC-compliant wireless communication modules were used to actuate lights. The entire systems were mounted on two 12’ x 2” square posts. Since these RRFBs are manufactured by Migma in Walpole, their cost is often the lowest on the market.
