Flashing Brakelights and hazards

Hello,

I would want to implement the same ESC system in like the ETK, Vivace which makes the brakelights flash on hard braking with hazards at the end or during a crash.

How could I make that for The Gavril Roamer ?

I tried to use the ETK ESC code in the roamer.jbeam file like this :
"controller": [
["fileName"],
["postCrashBrake",{"brakeThreshold": 60}],
["adaptiveBrakeLights"],
["vehicleController", {}]
],
"adaptiveBrakeLights": {
"indicateESCUsageWithBrakelights":true,
"activateHazardsAfterEmergencyBraking":true,
"blinkOnTime": 0.1,
"blinkOnffTime": 0.1,
}

This makes the hazards light come on when hard braking with ABS or having a crash, so good, but the tailight doesn't flash when hard braking.

Is it because the Roamer doesn't have the different ESC mode or doen't have an ESC file ?

How could I make the brakelights flash ?

Thanks.
