if(!strcmp(cmd, "/hazard", true))//hazard lights
    {
        if(IsPlayerConnected(playerid))
        {
            if(IsPlayerInAnyVehicle(playerid))
            {
                new newcar = GetPlayerVehicleID(playerid);
                if(CarFlasher[newcar] == 0)
                {
                    CarFlasher[newcar] = SetTimerEx("Flashers", 1000, true, "d", newcar);
                    CarFlasher[newcar] = 1;
                }
                if(CarFlasher[newcar] == 1)
                {
                    KillTimer(CarFlasher[newcar]);
                    CarFlasher[newcar] = 0;
                }
            }
        }
        return true;
    }

And this is the function:

forward Flashers(vehid);
public Flashers (vehid)
{
     ToggleVehicleLights(vehid);
    //your other code
    return 1;
}

Anyways, if you search there is already a filterscript about vehicle lights. Take a look at it and see how it was built, but don't just copy and paste, otherwise you will never learn.
