would this work ???   

connect the positive + wire to permanant live and negative- to ignition live, wen you turn your key the led will go out and when you turn the key off it will start flashing---

Yes, that should work fine. 

Just temporarily connect up a 12 volt flashing LED in the colour of your choice, and if it's OK, connect it up permanently.

You could put a diode in series just to make sure no current can possibly flow the 'wrong' way through the LED.

I find Maplins the easiest place to get LED's and the plastic clips for them.
