Wiring a Red Led Fake Alarm bulb in Ford Ranger?

If I wire a led fake alarm led bulb in my 2002 ford ranger what can I possibly wire it to so when I turn my ignition off the light bulb powers on and when I turn my truck on it turns off?

Yes.
Use a 12V relay that has a normally closed or change-over contact.
connect the coil to the ignition and earth, connect the contacts to power the LED and 12v.
Ignition power will switch the relay, opening the contact, the LED will go out.

It is just on all the time.
