Hey guys can someone please help me understand what the phases on whelen 500 linear super leds means. I have two light heads that are split red and blue. When they flash they are synchronized and flash both red and blue at the same time. I was told that you can change the order of the red and blue flashing to perhaps one that flashed red and blue and the other that flashes blue and red at the same time. It says the light has 69 patterns but one pattern has phase 1-4 so basically four options for that one patter. If this is possible how do u change the light head to the different phases. I was thinking of tapping one of the gray synch wires to a pos+ and see if that changes it but not sure. Any help would be appreciated
