Steering Wheels - Joysticks - Headsets - Gamepads

[Zipppy]

I have been trying over the past few months to toggle a button without mapping it to any keys on my G25, I want it to turn on headlights and turn them off when I presss it again, the game I am trying make it work in is Live for Speed, you can only flash your headlights, not turn them on and off . I did a similar thing to what I want, but in a program called XPadder, it only worked if I mapped it to a key on the keyboard, which in this case is "G" and it "held down" the key virtually. It always spammed my message input box with G's if I had it on.

Any help is apperciated.
