Yes, after flattenning my battery we put one on. A cheap 12v buzzer off ebay in series with a diode, one end connected to a permanent 12v supply, the other to the wire which is live after switching the lights on. Fitted under the steering column cover, cost about a pound and works a treat.

Quick wiring diagram or link to what you got? Crap at circuits, what stops the buzzing when you got the ignition on?
Actually I should have said the negative terminal of the buzzer goes to any wire which is live when the ignition is switched on and the buzzer positive connection goes to the wire to the headlights.
With the ignition and lights on, both terminals of the buzzer get 12v meaning no potential difference across the buzzer meaning no sound.
With the ignition off and the lights on the buzzer gets 0v on one wire, 12v on the other and therefore sounds.
With the ignition on and the lights off the buzzer will also get 0v on one wire and 12v on the other so may sound. I used a diode in series with the buzzer to stop it sounding in this case.
One of the most common general purpose diodes is "IN4001", you can get a pack of several for a few pennies on ebay. Any 12v buzzer will do.
