Sure. Newer cars automaticaly swith on warning lights (turning lights on both sides), at emergency braking.
ColorMFA put signal on this output if strong deceleration ( more than 0,6 g) is detected. Difference between both modes is continous or blinking output. So you can use a relay to trigger in car built blinking switch, or use relay direct connected to turn lights.
This fuction works excellent...

Thank you for the reply, but I need more info - what is the signal: ground or +12V? Do you have any wiring diagram for connecting this signal to the existing Hazzard button?

Outputs in ColorMFA are ground when active. I made a small circuitry with relay and two inputs - one for emergency braking and second for reverse gear (which signal is + 12V) - both switches warning lights on via built in hazzard switch.
Here is schematics. Transistor must be PNP, BD140 for example. I used universal 1 A diodes - 1N4004 for example.
In Passat b5 relay is paralel connected to hazard switch pins 1,2,3.

One more question - when the signal dissappears? When release the brake pedal or after some time after wheacle stops, or i need to stop it via hazzard switch manually?
