How do we output the air temp for use within the Dynamics Section. 
Trying to activate a bunch of anti-ice dynamics that rely on the air temp being below zero.
I have this already in the dynamics. I note this is used for graphics input's for MFD type but nothing found for dynamics use.

<[string8][Input][TemperatureSensor.Temperature]>

There is a temperature sensor object which outputs the temperature... Just search for "TemperatureSensor".
For the flashing lights: You can take a look at the Q400 caution and advisory system (master_warning_system) and Learjet 45. The CAS messages have a flash duration property which can be used for this exact purpose. All you need to do is add a logic_or for the input. This is the best solution if your aircraft has a master caution or master warning button the illuminates when any new caution/warning comes up.
Alternatively you can use the logic_confirm_delay and flasher_rectangle classes:
<[logic_or][FireDetected][]
<[string8][Inputs][ EngineFire.Output TurbineOverheat.Output ]>

<[flasher_rectangle][FireFlasher][]
<[string8][Input][FireDetected.Output]>
<[float64][Period][1.0]>
<[float64][FractionActive][0.5]>

<[logic_confirm_delay][FireConfirmed][]
<[string8][Input][FireDetected.Output]>
<[float64][TimeUp][5.0]>
<[float64][TimeDown][0.001]>
<[float64][Threshold][0.9]>

>Thanks Master. So we are just doing the flash logic inside the dynamics and not the graphics, it all makes sense now. Now that is a frightening thought
