They can flash simultaneously or alternating. The dual mode allows one color to steady burn or have one flash pattern and the second mode is able to do the same. Have a basic ‘slower’ flash pattern when stopped and on scene on mode 1 and a fast dual color pattern while responding.

The Duplex dual colour range is our latest addition to our Fusion family, these LED modules feature 6 x 3 Watt LEDs, 3 LEDs for each colour! There are 2 input wires, 1 for each colour so that each colour can be controlled separately and then when both input wires are connect both colours will alternate flash!

These really are an incredible invention along with the 180 degree optics insures extreme wide angle light output for maximum visibility.
