Flip flop 2 12v lights

I am looking for a simple circuit (or pre made device) that will allow me to "flip flop" 2 sets of 2 lights, controlled by a pushbutton switch.

In more descriptive terms, I have 2 sets of 2 lights each (red and blue) that I want to be able to control via 20 parallel pushbuttons. So the 2 red lights are on, any 1 of the buttons are pushed and the 2 blue lights come on, any 1 of the buttons are pushed and the red lights come back on..etc.etc.

Any ideas or suggestions ?

You could use a Set-Reset Flip Flop such as this. For high current you can substitute power N-MOSFETs for the bipolar transistors.
