The Ultimate Horn Solution is a covert security upgrade built for the Holden VF Commodore. We move your real horn somewhere a thief can't reach it, then fit a decoy in its place — wired so that any attempt to silence it sets the alarm off.
Thieves go for the horn before anything else — kill it and your alarm can scream to an empty street.
On the VF, the factory horn sits where a determined thief knows to find and disable it.
Getting at the horn or its wiring often means prying at a door or panel — costly damage on its own.
Once the horn's gone, the loudest, most effective part of your security goes with it.
Built in conjunction with Ultimate Conversion Wiring, the Ultimate Horn Solution relocates your real horn and replaces it with a booby-trapped decoy — so the move a thief makes to go quiet is the move that gives them away.
We move the factory horn to a concealed spot a thief won't think to look — so the horn that actually sounds your alarm stays protected and fully working.
A new factory-style horn goes back in the original position, wired independently of the real one. It looks completely standard — and like the obvious thing to disable.
Cut or disable the decoy and that action triggers your factory and/or IGLA alarm. The thief gives themselves away, while your door and wiring stay intact.
This isn't a generic add-on bent to fit. The Ultimate Horn Solution was designed specifically for the Holden VF Commodore, in conjunction with Ultimate Conversion Wiring, so it sits and behaves exactly like factory.
Whether you're running the factory alarm, an IGLA system, or both, the decoy ties straight in. Any attempt to silence your horn becomes the trigger — and it's a natural partner to a covert IGLA immobiliser.
A quick look at how the system relocates your horn and turns a thief's first move into a dead giveaway.
Every Ultimate Horn Solution is installed in-house by a licensed vehicle security specialist and authorised IGLA installer for NSW — not subcontracted, not rushed.
We don't travel to you. Your VF is fitted properly at our Kellyville or Wilberforce workshop, then tested before it leaves.
