Migma has recently installed one radar sign in Massachusetts. For this radar sign, when a vehicle is speeding, the display is shown in color of red, otherwise, in green. Instead of using one large battery and one large solar panel, Migma radar sign utilizes two 20Ah lithium batteries, and two 25W solar panels which are often aimed at Southeast and Southwest to ensure all day battery charging. Moreover, the entire unit is mounted on a utility pole. Because they are manufactured by Migma located in Walpole, MA, the radar signs are guaranteed to be low in price.
